WHY?

When deciding what to plot for our specific topic, we decided to take intoconsideration aspects that affect a glider or in this case, Silbos journey to theCanaries and we came to the conclusion that it would be most important to plotdata on wind speed, current speed, sea surface height and ship traffic.

What do we plot?

Why is wind speedimportant?

It effects the ocean

*Provides energy on theocean surface*

Causes ripples and waves*

Effects the size of thoseripples and waves*

Which could ultimately takea toll on the glider*

Why Current Speed?

Easy Formula:

Current Speed = Time = Battery Life

Slow moving currents =more time to reachdestination = more useof battery life

Fast moving currents =

less time to reachdestination = less use ofbattery life

Since the gliders have no propeller, they dependof ocean currents to glide their way through theocean, therefore the glider is a the mercy of thecurrents and that is why we decided to monitorcurrents because they are what determine Silbosability to reach its goal.

Important for the Mission

Sea surface height can possibly affectour window of recovery. If SSH is toointense (meaning high), chances of

recovery are lowered because we don'twant to risk crew members and/orequipment going out in 10m or sowaters. Ideally wed prefer SSH to below or manageable, as opposed to ahigh SSH where it would be dangerousto recover.

Shipping at the Finish Line

The islands exports are bananas, sugarcane, tomatoes, oranges, dates, and tobacco to Europe and theAmericas. Shipping traffic will affect Silbos recovery; the number of ships correlate with danger. More activity

results in a greater probability of collision and mission failure.

Silbo would approach the Canary Islands from the North or Northwest. The ideal recovery site would be in anarea with little to no commercial activity, yet still high in depth to reduce the risk of running aground.

Measurements of four out of the seven islands that comprise the Canary Islands were used in the making ofthese figures.

The types of ships recorded include passenger, cargo, sailing ships, pilot vessels and tugboats. Tourism is a bigpart of the economy with about 12 million tourists a year interested in everything from its four national parks towitnessing Canarian wrestling. Ferry boat rides between islands which can take from a one to two and a halfhours, can reach speeds of up to 30 knots (~35mph). Any sort of collision could lead to Silbo spiraling down toan abrupt end to the mission.

Conclusion

Overall we wanted to plot data that was relevantand useful in Silbos journey to the Canarieswhich is why we decided to plot: Wind Speed

Current Speed Sea Surface Height Ship Traffic

We would like to thank Enrique and his colleague for taking their time in helping us andallowing us to use their data.
