Update on IMOS projects Status July 2015

• Lucinda Jetty Coastal Observatory

• Bio-optics at NRS sites under ANMN (EcoTriplets, WQMs)

• IMOS Ocean Colour • Continuous above water radiometry - DALEC • Bio-optical data base• Production and validation of Ocean colour

IMOS Bio-optical WG meeting 1-2 July 2015, Perth

Lucinda Jetty Coastal Observatory (LJCO)

• Quasi-operational data acquisition re-established in early 2014 Continuous measurements + fortnightly water sampling

• Full in-water IOPs and above water AOPs (details next slides)

• Received TC-Yasi insurance claim – instrument refresh

• Currently funded until June 2016 (not part of IMOS core funding)

• Exploring options for external funding

Update on bio-optics at NRS sites (ANMN)

• EcoTriplet deployment & analysis • WQM analysis – site specific regression against HPLC

(update from Lesley)

Funding continues 2015/16 and 2016/17 (~20% cut)

Bio-optics at NRS sitesRe-evaluation – recommendations for 2015/16

On-going• Site characterisation – seasonal variability using OC

Signal-to-noise limitations – clear waters? • Follow-up with manufacturer on non-physical raw counts

2015/16• Pause deployments? • Perform local calibration – frequent inter-comparisons

Scattering Hobart – CDOM Townsville?• Add CDOM to monthly in-situ sampling – perform field

characterisation on sensors (determine scale factors)• Were feasible reduce instrument rotations per site

Updates on IMOS Ocean Colour (OC)

• DALEC - Continuous above-water radiometry(J. Lovell, D. Boadle)

• Bio-optical data base(L. Clementson, H. Franklin)

• Production and validation of OC(E. King, R. Scott, K. Suber, J. Lovell)

Funding continues 2015/16 and 2016/17 (~20% cut but large carry forward to buffer reduced funding)


Continuous above-water radiometryAll DALEC data since 2011

Transects of above water radiance and irradiance → objective reflectance

Continuous above-water radiometryQuality controlled DALEC data

Reflectance conversion possible for above transects

OC3 inverted DALEC reflectance spectra off WASouthern Surveyor 21 Aug – 11 Sep 2011 + MODIS median composite overlay


New National Marine Facility delivered Sep 2014Not an ideal platform for the DALEC


No support by MNF to operate the DALEC – maintenance overhead too highVessel structure impacting on radiometry (irradiance)2015/16 Solander only – allocation provided to AIMS to support deployments

IMOS bio-optical data base Continued acquisition of bio-optical data from the Australian research community into the IMOS bio-optical data base and data provision to NASA (SeaBASS) and ESA (Mermaid) as well as ESA’s Ocean Colour Climate Change Initiative (OC-CCI).

Focus 2015/16Inclusion of AIMS & JCU data sets

Data updates to SeaBASS (Jan-June 2014)

Ocean Colour Validation

(Image credit J. Lovell)

• New in 2014/15 sub-facility will start providing annual validation reports

• Based on bio-optical data base – match-up analysis

• Provision of extracted satellite data & associated match-ups

• Possible – ocean colour time series from “virtual buoys”
