The Sitka sea lion became famous this summer for refusing to go back to the waters for three days:
Crews in Sitka have had their hands full the past few days as they tried to get the adult male sea lion back into the water. On Monday afternoon, attempts were finally successful.
NOAA Alaska region spokeswoman Julie Speegle said the 1,500-pound stellar sea lion was tranquilized and transported back into the ocean using a front loader and flatbed truck. The operation started at 1 p.m. and took about an hour and a half to complete.
The team transported the sea lion back to the beach. Upon waking, the sea lion entered the ocean and swam away. Speegle said he was last seen catching a fish. [Source]
Turns out he has swam quite a bit since then!
NOAA put a tracker on the marine lion and were surprised to find that he traveled From Sitka to Marmot Island near Kodiak a total of 594 nm (1100 km).
A nautical mile is a unit of measurement defined as exactly 1,852 metres (6,076.1 ft; 1.1508 mi). Historically, it was defined as one minute of latitude, which is equivalent to one sixtieth of a degree of latitude. Today, it is a non-SI unit which has a continued use in both air and marine navigation, and for the definition of territorial waters.
One tenth of a nautical mile is a cable length. [Source]
