Early winter Boston Harbor
TASL census summary:
1980 - 2006

This is the updated version of the table originally presented in Early winter TASL censuses in Boston Harbor: A summary of results 1980-1997.

We have completed 20 years of TASL Harbor early winter censuses. There were no November counts in 1984 - 1987. The November 2002 TASL census was cancelled because of poor visibility due to bad weather.
