OWOC’s second formal Whale Shark search of 2014, and our first search in the Ewing Bank area(WS2-EB1)

On this second search of the season for whale sharks, we were excited to visit the area that historically has always been visited by large aggregations of these gentle giants of the sea — the Ewing Bank area, a wide shelf located about 200 miles south-southwest of New Orleans.  This was still early in the year, as previously the large groups have been spotted here in June.  But there had been some reports from fishermen of sightings, so we were ready and eager.

What we found was heartening — lots of dolphins and large tuna, bonito, and other fish (even some marlin!), but alas, no whale sharks.  The sargassum was gorgeous and there was lots of it. There were also many areas of surface oil sheen, some around platforms and drillships, some sitting in apparently isolated areas (pipeline leaks or natural seeps, hard for us to say).

Here are maps showing our flight survey of today. The icons indicate substantial sightings — of sargassum, of bait balls (mostly bonito and smaller except for some larger fish near some of the platforms), groups of dolphin with large tuna and a sighting of some marlin, and surface oil pollution, and some of the more interesting platforms and cargo and drillships.
