Questions About Gray Whale Migration Data

What is the main thing you notice about the number of sightings at both California counting sites in the past two weeks?

 

 

 

 

 

During March 31-April 13 last year, ACS/LA observers spotted 14 cow/calf pairs. Gray Whales Count had reported 9 cow/calf pairs. How do numbers of calves compare so far this season at the

(1) Los Angeles site?

 

(2) Gray Whales Count site?

How many no-whale days were recorded at each site during this period? Why do you think a zero is recorded on no-whale days instead of leaving the space blank?

The first pulse (adults, juveniles) has passed. The second pulse (cows/calves) has not yet peaked. What changes do you expect when your next data come in two weeks?
