Oceanographers do a repeat research cruise in the spring each year. Lucky for us the ship has every Star Wars movie for an annual May the Fourth be with you marathon.
We started on May 4 GMT just to make sure we had enough time for science and movies. 😂 #DY2504 🧪🌊

Geese are seen flying next to the research vessel NOAA Ship Oscar Dyson in the Bering Sea.
We think these are cackling geese, perhaps the Aleutian subspecies (with a little help from a Frosty friend 😉).
Are we oceanographers or birders? 🧪🌊🦑🪿
