Executive Summary
A benthic sediment sampling survey (GA0356) to the nearshore areas of outer Darwin Harbour was
undertaken in the period from 03 July to 14 September 2016. Partners involved in the survey included
Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Department of
Environment and Natural Resources within the Northern Territory Government (NT DENR) (formerly
the Department of Land and Resource Management (DLRM)). This survey forms part of a four year
(2014-2018) science program aimed at improving knowledge about the marine environments in the
regions around Darwin and Bynoe Harbour’s through the collection and collation of baseline data that
will enable the creation of thematic habitat maps to underpin marine resource management decisions.
This project is being led by the Northern Territory Government and is supported by the INPEX-led
Ichthys LNG Project, in collaboration with - and co-investment from GA and AIMS. The program builds
upon an NT Government project (2011-2011) which saw the collection of baseline data (multibeam
echosounder data, sediment samples and video transects) from inner Darwin Harbour (Siwabessy et
al. 2015).
Here we present an account of the field methods and data summaries (location maps and
comprehensive metadata) for the collection of 200 seabed sediment samples designated for grain size
and inorganic elemental analyses, and organic matter concentration, source and reactivity measures.
Metadata is also provided for seagrass observations and hardground occurrences. The seagrass
observation data will be incorporated into DENR’s seagrass database.
The baseline environmental datasets acquired during this survey will be merged with like datasets
from three other surveys conducted as part of the overall project to create a set of interpolated maps
of abiotic parameters with full coverage for the region. Some of the maps will be integrated into final
habitat mapping products. Baseline data from the survey will also be made publically available via the
Geoscience Australia website (http://www.ga.gov.au/).

1 Introduction
This report summarises metadata and procedures undertaken during benthic sediment sampling
survey GA0356 to the nearshore areas of outer Darwin Harbour in 2016. This survey forms part of a
four year (2014-2018) science program aimed at improving knowledge about the marine environments
of the regions around Darwin - Bynoe Harbour (henceforth known as the Darwin – Bynoe Harbour
region). Through the collection and collation of baseline data, thematic habitat maps that underpin
marine resource management decisions will be created. This project is being led by the Northern
Territory Government and is supported by the INPEX-led Ichthys LNG Project in collaboration with -
and co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science
(AIMS). The program builds upon an NT Government project (2010-2011) which saw the collected
baseline data (multibeam echosounder data, sediment samples and video transects) from inner
Darwin Harbour (see Figure 1-1; Siwabessy et al. 2015).
To deliver this program, the joint partners (NT DENR, AIMS and GA) identified four core tasks to
undertake in the region, which were:
1. To obtain high resolution bathymetric and backscatter data;
2. To examine the abiotic patterns important to benthic communities;
3. To characterise the benthic fauna and flora; and
4. To model species/community distribution.
The Darwin - Bynoe Harbour region was subdivided into four study areas for the purpose of data
acquisition (Figure 1-1;Table 1-1). Suites of benthic sediment samples were collected together with
tidal data and full coverages of multibeam bathymetry data from outer Darwin Harbour and outer
Bynoe Harbour during two previous surveys (SOL6187 and SOL6432) held in May/June 2015 and
May 2016 respectively (Table 1-1; Figure 1-1). Detailed accounts of the work undertaken during these
surveys, and a more comprehensive compilation of background information pertaining to the overall
program, are provided in two post-survey reports (Siwabessy et al. 2016; Siwabessy et al. 2017).
The current report pertains to the Darwin Shallow Water survey region (Table 1-1), which comprises
~250 km2 of nearshore area in outer Darwin Harbour, at water depths <5 m (at Lowest Astronomical
Tide (LAT)). The aim of the sediment sampling component of these surveys was to collect benthic
sediment samples to enable seabed characterisation in terms of the abiotic variables that influence
benthic community patterns, consistent with task #2 above. Grain size, carbonate, inorganic element,
sediment oxygen demand (SOD), and organic matter (OM) concentration, source and quality variables
(Table 1-2) will be derived from these samples. The scientific basis of the parameters under
investigation is reviewed in Radke et al. (2017), which highlights that OM quality (e.g. the freshness or
degradability of OM) is an important control on invertebrate nutrition (Danavaro et al. 1995) and thus
relevant to habitat mapping. The variables will be spatially interpolated and the resulting maps will be
interpreted from a process-orientated perspective (see for example Radke et al., 2011). The grain size
samples will also be used to calibrate the backscatter data.

When finalised, the datasets will be made publically available through the GA website
(http://www.ga.gov.au/), and the scientific results of the surveys will be described in a final report that
will synthesise all data collected in the program.

1.1 Study area
The Darwin – Bynoe Harbour region lies in the eastern part of the Beagle Gulf, which is located
between the southern shores of Melville and Bathurst Islands and the Australian mainland
(Figure 1-1). This region includes Port Darwin, outer Darwin Harbour (waters between Gunn Point and
Charles Point and includes Shoal Bay) and Bynoe Harbour region, which is bounded by Cox
Peninsula in the east and five islands in the west. The total area of interest is about 2000 km2.
Darwin Harbour is a tropical estuary formed within a drowned river valley, located on the northwestern
coast of the greater Joseph Bonaparte Gulf, northern Australia. Darwin Harbour is positioned
approximately 12.5° south of the equator, facing Bathurst and Melville Islands and the Timor sea,
across the intervening Beagle Gulf (Woodroffe et al. 1988; Nott 2003). The geology of the Darwin
Harbour consists of a channel incising into two adjacent Proterozoic units that are overlain by
sediments of the Darwin Harbour member of the Bathurst Island Group (Cretaceous) on the adjacent
land. The boundary between these Proterozoic units, the Welltree Metamorphics on the western side,
and the Burrell Creek Formation on the east, is located under the main channel (Darwin Sheet SD 52-
4, Northern Territory Geological Survey, 1988). Darwin City is located on the largely horizontally
bedded strata of the Darwin Harbour member, overlying Burrell Creek Formation sediments (Nott
2003). During the Last Glacial Maximum (19-23 ka BP) Darwin Harbour and the adjacent Beagle Gulf
were without marine water, and subject to subaerial erosion and weathering processes. While
Holocene sea level and sedimentary processes are well documented (Woodroffe and Grime 1999,
Woodroffe et al. 1993), less is known about the post Cretaceous to Holocene history of this area.
Several lines of evidence suggest that the greater Joseph Bonaparte Gulf region was affected by
global low sea levels similar to the last ice age since at least the end of the Mid Pleistocene Transition
(~ 650 ka BP) with buried river channels present just outside Beagle Gulf (Bourget et al. 2013, Saqab
and Bourget 2015, Nicholas et al. 2015). For the majority of this time, sea level was insufficiently high
for Darwin Harbour to be an estuary. Thus, Darwin Harbour is a drowned river valley which has been
exposed to erosion and weathering for a large proportion of the past 650 000 years, and has only
been intermittently connected to the sea over that time. Estuarine conditions similar to present were
established some 7 to 8 thousand years ago, just as rising sea levels stabilised after the last ice age
(Lewis et al. 2013).
The climate regime is monsoon tropical. Darwin receives about 1726 mm of rainfall annually, with the
majority falling in the monsoon (wet) season between November and March. Runoff varies between
250 and1000 mm of annual rainfall. Riverine discharge is low as the Darwin and Bynoe harbour
catchments are relatively small. Prevailing winds are seasonal with north-west monsoons in November
to March giving way to southeast trade winds from May to September. During the wet season, the
monsoonal conditions create turbulent wave action and thus high turbidity levels along this coast.
The annual range in sea surface temperature in Darwin Harbour is from 23 - 34°C. The Beagle Gulf is
dominated by tidal currents that flow in an east-west direction. The main direction changes to
northwest–southeast near the entrance to Darwin Harbour. The tides amplify as they transit across the
wide continental shelf and the currents become more bidirectional as they approach the coast. Darwin
and Bynoe harbours have a large tidal range (macrotidal) with a 7.9 m maximum tidal range (5.5 m
mean spring range and 1.8 m mean neap range) (Woodroffe et al. 1988, Andutta et al., 2013). The
tidal cycle is semidiurnal (two tidal cycles are experienced every 24 hours). Tidal currents can reach
up to 2 m/s (7.2 km/h) during a maximum spring tide (Andutta et al. 2013; Williams et al. 2006). As a
result of the tidal energy, Darwin Harbour is considered to be a reasonably well-mixed homogenous
water body that is naturally turbid but carries low nutrient loads. Turbidity values range from 5
Nephelometric Turbidity Units (NTU) in the dry season to in excess of 400 NTU during wet season
storms.
10
Darwin Harbour contains a main channel, and three elongate arms: West Arm, Middle Arm and East
Arm (Figure 1-1), each with a distinct catchment. The drainage basin of Darwin Harbour is 1833 km2
(Andutta et al. 2013). The Elizabeth River flows into East Arm, while the Darwin/Berry and Blackmore
Rivers flow into Middle Arm. West Arm is without a prominent river. Each arm comprises deeper
channels bordered by intertidal and subtidal mud flats, and these are in turn fringed by mangrove
forest (Fortune 2006). The seabed morphology of the harbour and estuary is dominated by a large
river channel and adjacent shoreline platforms and subtidal flats (Siwabessy et al. 2015). The main
channel was previously estimated to be 36 m deep, and channels in the individual arms up to 12 m
deep (Fortune 2006). Tides dominate sediment transport, while the effects of wind-driven currents,
waves and river discharge appear negligible for sediment movement (Andutta et al. 2013). Turbid
plumes can extend over wide areas of the harbour. While large parts of the river channel are free of
sediment cover, most areas are dominated by unconsolidated sediment forming a wide variety of
morphologies including mud flats, ripples, sediment sandwaves and even sub-aqueous dunes. These
sedimentary features are the result of the erosion, transport and deposition of sediment in currents
during calm and stormy conditions.

2 Methods
2.1 Survey overview
The survey was undertaken using small vessels in the period between 3 July and 14 September 2016
(Appendix A). Typically, benthic sediment samples were taken from 3 - 5 pre-selected waypoints (e.g.
point locations) on a given day, during the early morning hours. The waypoints sampled each day
were determined by the prevailing weather and tide conditions.
2.2 Station selection
A set of 100 waypoints (Appendix B) were pre-selected to serve as sampling locations (or stations)
(Figure 2-1). The survey area was spatially stratified into 25 strata using latitude and longitude data;
and then four waypoints were randomly selected within each stratum. The R packages sp (Pebesma
and Bivand 2005), raster (Hijmans 2014) and spcosa (Walvoort et al. 2015) were used to operate and
plot the data.
A small number of samples (designated as ‘other’ in Figure 3-1) were also collected from locations that
were not pre-selected waypoints. These samples will be used as potential end-members for
geochemical interpretations (e.g. three soil samples, one mangrove sample and seabed samples from
the mouths of Buffalo Creek, Rapid Creek and the King’s River).
The sampling locations were assigned station numbers when they were first sampled. The station
numbers were given in the order of collection and thus are different from the waypoint numbers
(Appendix C).

2.3 Sample collection
Unconsolidated seabed sediments were collected at each station using a box corer and/or a Shipek
Grab. The Shipek Grab measures 10.1 x 16.2 cm in area and is 8 cm deep, and collects up to 970 ml
of sediment (and porewater) (Figure 2-2). It is designed for sandy sediment. The box corer measures
15 cm X 15 cm X 24 cm (~5400 ml) and is only able to effectively collect muddy sediments (Figure
2-2). The grabs were hand deployed and retrieved, sometimes with the aid of a winch. Up to four
samples (grab and/or box core) were taken at each station, as required, to get sufficient sediment for
up to six sub-samples. The sub-samples were designated for: (i) grain size analysis; (ii) chlorin
analysis; (iii) SOD; (iv) Total sediment metabolism (TSM); (v) core incubation experiments (e.g.
13
benthic TOU and TCO2 fluxes (on up to three samples per day)); and (vi) element, carbonate and
specific surface area analyses (Table 1-2). Every grab and box core from which a sample was taken
was assigned a unique box core or grab number, in the order of sampling. Metadata (e.g. latitude,
longitude, water depth, date and time) were also recorded when every grab and box core was on the
seafloor (Appendix C). The grab and box core did not work at some waypoints (e.g. over hard ground),
and at some stations recovery was not sufficient to obtain all six sub-samples. Grain size samples
were given highest priority and TSM was given lowest priority. A summary of the sub-samples
collected at each station, and the grab/box core numbers that were assigned to these samples, is
provided in Appendix B.

2.4 Sample analysis
Samples were returned to the laboratory at the AIMS Arafura Timor Sea Research Facility (ATRF) as
soon as possible after collection, where they were further processed and/or stored. The procedures
that were undertaken on the sub-samples, both on the boat and at the ATRF, are summarised in
Table 2-1. Details of field (field) and laboratory (ATRF) processing used to prepare and analyse the
sub-samples. The sub-sample ID extension (_A1, _B1 etc.) correspond to the file extensions assigned
to parent sample ID’s (Appendix C) in GA databases. Thus each sub-sample has a unique ID (and
sample number).. Upon completion of the fieldwork, the sub-samples were sent to GA for further
laboratory analyses by procedures that are described in Radke et al. (2015, 2017). These laboratory
procedures are identical to those undertaken on like sub-samples from the previous two surveys
14
(SOL6187 and SOL6432). However, samples collected during surveys SOL6187 and SOL6432 were
immediately processed in the shipboard laboratory of the RV Solander.

3 Data summary
3.1 Sample and sub-sample locations and metadata
Two hundred seafloor sediment samples were collected from 95 stations during the survey: 167 from
Shipek Grabs and a further 33 from Box Cores (Table 3-1). During the time period of the survey, 200
incubation experiments were undertaken. Sub-samples were also prepared for grain size, chlorin, and
elemental, carbonate and specific surface area analyses (Table 3-1). The location points for each the
various sub-sample types are shown in Figure 3-2 to Figure 3-7, and the metadata for the sub-
samples is provided in Appendix E to Appendix J (Table 3-1).
A single ‘specimen’ sample was collected at Station 40 (Figure 3-8) comprising brown laterite pellets.
These pellets, which are designated for elemental analysis, are ubiquitous throughout the Darwin -
Bynoe Harbour regions, and are derived from the coastal conglomeratic lateritic rocks described by
Nott (2003). Elemental analysis of similar specimens collected at Station 56 during survey SOL6187 to
the deeper-water areas of outer Darwin Harbour revealed that such pellets are enriched in As, Pb, Cr,
V and Cu relative to the residual sediment matrix, and have a strong impact on the bulk sediment
chemistry.
Seagrass roots and or fronds were observed in 19 of the seabed samples (Table 3-1) collected in the
western part of the study area (Figure 3-8).The metadata for the seagrass observations, including
cursory identifications, is provided in Appendix L. The seagrass data has been provided to DENR for
inclusion into their seagrass database.
Samples could not be taken at three of the waypoints due to the occurrence of hardground. These
locations are shown in Figure 3-8.

3.2 Preliminary observations
The baseline environmental datasets acquired during this survey will be merged with like datasets
from the other three surveys to create a set of interpolated maps of abiotic parameters with full
coverage for the region. For example, below we include a preliminary interpolated map of the benthic
TOU flux, which combines the core incubation experiment results from the three completed surveys
(Table 1-1; SOL6187, SOL6432 and this survey). Benthic TOU fluxes are an indicator of benthic
carbon mineralisation rates (Glud 2008), which are an indicator of carbon loading to the seabed (Eyre
and Ferguson 2009). The preliminary map shows that carbon loadings were relatively high in the
western part of outer Bynoe Harbour and in the nearshore areas of outer Darwin Harbour (this study).
However, the benthic TOU flux average (± 1 s.d.) for the combined dataset was only 15.3 ± 7.9 mmol
m-2
d-1
, which is considerably lower than average fluxes measured in subtidal and intertidal sediments
in inner Darwin Harbour (65 ± 24.6 and 76.7 ± 28.8 mmol m-2
d-1
respectively) (Burford et al., 2008),
and the range reported for tidal creeks in Darwin Harbour (40 - 90.5 mmol m-2

sewage contaminated Buffalo Creek (Smith et al. 2012). Annual dry season carbon loads for the
region will be estimated from these and other data after the completion of the nearshore survey of
Bynoe Harbour.

Figure 3-9 First pass interpolated map of the benthic total oxygen uptake (TOU) flux measured in mmol m-2
d-1
incorporating data from three of four surveys (Table 1). The spatial predictions of TOU were made using the default options for the inverse distance weighting (IDW) technique in ArcMap. Note that the interpolation is not relevant in the areas without stations. More advanced statistical modelling techniques will be used to derive continuous spatial coverages for various physical parameters when the fieldwork is complete and the final datasets are assembled (see for example Li et al., 2010, 2011).

Metadata for Grab Samples Appendix C
Appendix Table C. Metadata for the ‘parent’ grab samples arranged in the order of sample collection. Each child sample or sub-sample (Appendix D) connected to a parent
has the same metadata as the parent sample but a different sample number. In addition, the Sample ID’s of the sub-samples include the parent sample ID and an extension
that reflects the type of analysis undertaken. For example, GA0356/004BC006_A1 designates a sub-sample from parent sample GA0356/004BC006 from survey
GA0356 (this survey) collected at Station 004 from Box Core (BC) 006 for the purpose of grain size analysis (_A1). Likewise GA0356/009GR004_B1
designates a sub-sample from parent sample GA0356/009GR004 from survey GA0356 (this survey) collected at Station 009 from grab (GR) 004 for the
purpose of chlorin analysis (_B1).

List of sediment sub-samples Appendix Daccording to station
Appendix Table D. List of sub-samples designated for geochemical and sedimentological analysis. Box
core and grab numbers are shown in the columns. Each of these sub-samples (or child samples) is
connected to a parent sample (Appendix C), and has the same metadata. However, the sub-samples have
different sample numbers than the parent samples. Moreover, the Sample ID’s of the sub-samples include the
parent sample ID and an extension that reflects the type of analysis undertaken. For example,
GA0356/004BC006_A1 designates a sub-sample from parent sample GA0356/004BC006 from survey
GA0356 (this survey) collected at Station 004 from Box Core (BC) 006 for the purpose of grain size
analysis (_A1). Likewise GA0356/009GR004_B1 designates a sub-sample from parent sample
GA0356/009GR004 from survey GA0356 (this survey) collected at Station 009 from grab (GR) 004 for
the purpose of chlorin analysis (_B1).SRS in the sample type position denotes surface regolith (or soil)
samples.
