Silbo continues the never ending story of the challenger mission as he maintains his course on the way to the western side of Madeira.
Conditions all seem to be alright for our little droid as he continues making smooth dives to 1000m with no evident sign of biological interference, calm weather, and a path clear of any shipping vessels.
Marine conditions from our three data sets, hycom, myocean, and ncom/nlom all continue to show the strong current flowing south from our location, which we are seeing push Silbo slightly to the south. However, we have turned on the current correction feature on this afternoon so Silbo will show signs that he is fighting the current to try and stay on a straight path to the current way point just to the south of Madeira. Below is the imagery from our ocean models:
In the HYCOM images above (Fig 2-5), we can see how strongly the geostrophic flow of the ocean dictates the salinity, temperature and density of the surface waters as we can see evidence of the eddies in all four images.
In the above images (Fig 6-11), we see the surface conditions and that of which is at 200m, 600m, 800m, and 1000m form the MyOCEAN models of temperature, height, salinity, currents, and the overall eastward flow of the water. These all continue to show a similar story to the hycom models of showing the eddy filled progeny of the tail end portion of the Gulf Stream.
Finally the ncom/nlom model of the land scape also shows the same as the above figures of the whereabouts of the eddies and similar movements of the currents.
Overall, we will wait and see how Silbo now flies these currents with the addition of current correction on as we continue on our way towards Madeira, remembering in the back of our minds that we are aiming to be there around the 17th- 20th.
