This from New York 1:

A necropsy will be performed today on the baby whale that died in Brooklyn’s Gowanus Bay.

After some problems, the 12-foot-long minke was hoisted onto a boat
this morning and taken to Jersey City where marine biologists will try
to determine the cause of death.

A tow line fell off the whale this morning, sending the body 30
feet below the surface. Police divers were able to reattach the line.

The 15-foot whale died yesterday, after breaching itself near Clinton Street.

The whale was first spotted earlier this week off the piers near 22nd Street and was seen swimming in circles.

Members of the Riverhead Foundation originally hoped the whale
would swim out to sea, but they say the animal had numerous cuts and
bruises and was swimming in an altered pattern.

They say it may have come in contact with the pier or other submerged objects.
