This is what's left of the old Sea Scallop Page. Please consider it a work area, containing some items that have not been integrated into the new page, many that have, and lots of examples of html tags that work in spite of the author. It will be completely integrated and deconstructed as time allows. Sorry for the inconvenience.

What would you like to see here in the near future?

Here's a start on some ideas

But hold on, all the buttons aren't wired in yet

Westport/Seastead Scallop site off Martha's Vineyard (no graphics yet)

This S-K funded project, proposed in 1995, was the first 'official' move toward
designating specific areas for scallop growout. It is a 3 x 3 mile square
about 8 miles south of Martha's Vineyard.


 

What does a sea surface temperature timeseries have to do with scallop?
After looking at it closely, the location of newly settled scallop juveniles
show correlation with the position of persistent temperature fronts.

  Ocean Color images from SeaWiFs instrument aboard the Sea Star satellite

Here's a SeaWiFs image (188k) after the heavy rains in the fall of 1999
that shows pretty clearly why sea scallops are not often found south of
Cape Hatteras. Note optically clear Gulf Stream water to the south.

Current Modeling and Simulations

Scallop larvae are bouyant for 35-45 days.
How far can scallop larvae drift during this time?
What areas may serve to reseed other areas?

Try out the Dartmouth College Numerical Methods Laboratory
interactive drifter simulations
(http://www-nml.dartmouth.edu/DROG3D/DROG3D.shtml)

here's a sample of multiple start points running 40 days.

Start points were selected from known scallop fishing areas. One observation from this is that the path of larvae seems to bypass the inshore Mass Bay areas using the 'average' monthly conditions approach.

try out the new Current Modeling and Simulation page (~440k and under construction)

or go directly to the source to install on your own system (2.6MB)

Craig Lewis simulations of scallop larval transport.
     from the Georges Bank Closed Areas. Select the 2.7 MB file in the lower righthand corner

For downloading and viewing animations on your own machine, first download and install the fli/flc player (~150k) from the Rich Signell website (or elsewhere). Animations can be selected most easily from within the player if fli/flc files are installed in the same directory

There are many other animations that use this format, so it is quite useful


 

What are some of the things we already know
about the Atlantic sea scallop?

Comparison of Overall US Scallop Landings to Maine Landings

meat weight in pounds

It appears quite possible that an increase in Gulf of Maine landings is followed by an increase in overall US (primarily Georges Bank) landings.
More careful work in this area is needed. Data from NMFS, Maine DMR, C. Findlayson


 

Japanese Scallop Landings (whole weight in metric tons)

Now, how do you suppose they did that?

with any luck this image will be rescanned before too long


 

Converting units and combining the data from both graphs

Conversion factor whole weight to meat ~8:1

so 550,000mt whole = ~70,000mt meats or ~150,000,000 pounds

it's the best we have for now

Another aspect of this comparison is that the seafloor area used in Japan to achieve this production is relatively small. In the US, the oyster industry in the state waters of Connecticut produces about the same landed value within 3 miles of the beach as the US Atlantic scallop industry produces using a significant fraction of the continental shelf.
