The fish are biting!

The morning was balmy and the sea was calm, but on the starboard side
of RV Melville, there was a frenzy of activity, both
in the water and on deck. Dave Grimes, one of the Able Seaman
(AB) on board, spotted a large school of mahi mahi that were
feeding on squid and flying fish. We could see the flying
fish scooting across the water, trying not to be eaten by
the bigger mahi mahi. A few of the mahi mahi were not so
lucky. Instead of having a nice squid breakfast, they were
caught by Dave. He landed several of these beautiful and
delicious fish. We are looking forward to dinner tomorrow
night. Can you guess what will be on the menu?
We ended the DSL-120 sonar survey today in this
area of the East Pacific Rise crest. Everyone on board is tired,
but were also happy because our work has paid off. We collected
a great set of data on the seafloor. The scientists on board will
continue to stand their watches, working on the information we
have gathered over the past three days. Our students are monitoring
the ships multibeam sonar system, which is gathering data
to create new seafloor images as the ship moves over it. The students
are also checking the DSL-120 sonar logs and editing the information
they entered into the logging computer. Other people are processing
the DSL-120 sonar data to produce final images of the seafloor
terrain and high-resolution bathymetric maps (that is, highly detailed
seafloor maps). We are headed to our next surveying site at 3°20N,
another site where the hydrophone array indicated an underwater
volcanic eruption has recently occurred. We started at 1600 hours
this afternoon. We have 416 nautical miles to go and we are making
12.5 knots (nautical miles per hour). When do you estimate we will
get to our next survey area? Ill give an update tomorrow
with our speed and how far we have left to go.
