Right Whale Migration Update: April 12, 2000
Greetings from the Stellwagen Bank National Marine Sanctuary.
This year's migration reports on right whales have been somewhat skimpy due to the lack of whale sightings in parts of their range. The few whales that did show up in the calving ground, and the scientists who traveled to study them, have cleared out for other waters.
The Final Tally for Winter 1999-2000
The final tally was one definite calf, and an unconfirmed second sighting. The researchers are now setting their sights on the possibility of seeing that one calf, and possibly others in the northern spring and summer feeding grounds. The one hope the researchers have is that they might have missed a calving area There may be one that was either further offshore, or north or south of the section of ocean that was patrolled. In the past, a few calves showed up in the feeding grounds that had not been seen down south. We can hope this is the case this year.
Mysterious Whales, Where Are You?
In late summer-early fall, the whales have tended to congregate in the Bay of Fundy and off the southern and eastern coasts of Nova Scotia. While numbers can reach several score ("score" means 20), there are still a large number of missing whales that are out there somewhere. Where are the whales? This is a research question that researchers are working on right now.
YIKES! Big Whales and Bigger Ships Share Channel
In April and May, as copepod concentrations shift with changing water temperatures and water movements, the whales have tended to move out into the Great South Channel, a deeper passage between Nantucket and Georges Bank. All three of these areas have been named right whale critical habitat by the U.S. government. The Channel, unfortunately for the whales, is part of the coast that also serves as the major shipping channel for north-south movement of large ships.. This area is a lot less accessible to whale protection patrols than the southern grounds or Cape Cod Bay.
Look at the Ocean Floor
Find a map of the eastern United States that shows the topography of the ocean floor. Study the water depths around Cape Cod and find Nantucket Island and the Nantucket Shoals. Look for Georges Bank to the east (between 40 and 42 degrees north latitude)and then see how you would answer this next challenge question.
That's all for this week. This is Anne Smrcina, education coordinator of the Stellwagen Bank National Marine Sanctuary, signing off.
