PLOCAN::MaReS Summer School

Friday, August 5th, 2011

The Oceanic Platform of the Canary Islands (PLOCAN) is a general marine science and technology mobilisation initiative that seeks to obtain the international socioeconomic business competitiveness derived from access to the oceanic space. PLOCAN is working in different fields as renewable energies, focused in ocean's energy resources, oceanographic buoys and underwater vehicles.

As one of its most important areas, PLOCAN Training Program has been working in the last year with underdegree students and graduates, mainly with Spanish students.

But this summer we are carried out the MaReS Summer School, an international initiative with the collaboration of Rutgers University, University of Madeira (Madeira Tecnopolo), and with the University of Azores, with an international student exchange program.

Two of our MaReS Summer School students are now in RU-COOL helping with SILBO glider mission between Reykjavik to Las Palmas.

"..You have grown up, Median...." Saruman in "the lord of the rings"

Hey guys,

Nilsen and Antonio speaking.. Definitely, Silbo has grown up. He flew 1048 km in 42 days (25 km/day) at 1,05 km/h (0.29 m/s). Now it is official: Challenger has joined the VIG (Very Important Gliders) Club !

A feet (> 1000 km run)  that has only been accomplished by a handful of gliders before now, including Rutgers Electric Gliders RU 15 (first long distance, international flight from NJ to Halifax, Nova Scotia) RU 17 (first attempt at crossing the Atlantic), RU 26 (1000m+ runs off of St Thomas and in the Ross Sea in Antarctica), RU 27 (The first Atlantic Crossing) and Thermal Gliders Cook & Drake (attempts at crossing the Atlantic at the 26.5° latitude).

But now lets zoom back in to the Northern Atlantic where Challenger 1 is continuing to make his way south. We have suffered 15 storms since the beginning.  One each 3 days. However, today it looks sunny in the North Atlantic.

Fig 2. Weather conditions 5 aug 11.

Definitely we are leaving the convection belt area of the North Atlantic determined by a high salinity and W NW flow of the currents over the silbo geographic domain.

Current path becomes clearer now and submesoscale dynamic seems to determine the day by day of silbo. Thus, over the past couple of days, we have been discussing a possible change of way point as we have come across another solar system of warm and cold eddies.

clockwise  planets (warm eddies)

One possible path to take would be to weave our way south by catching the west side of the cold core eddy to our south (which rotates in a counter clock wise manner) which hopefully will drag us south and to the east where we will then catch the strong southerly currents of the large warm core eddy further to our south.  The warm core eddy, which rotates clock wise, will hopefully then pull us further to the south and beyond.

Finally we would like to congrat to all of you (RUcool, TDW, ULPGC, PLOCAN), great team, for your great job and for this new great success.

Today we wish you all

force, wind, sea and honor
