This was the 8th day of the Maritime Mathematics Summer Institute for Teachers offered jointly by Bridgewater State College, Southeast PALMS Coalition and the Schooner Ernestina Commission. The first five days took place at BSC and this week is in New Bedford. Two days are aboard the schooner with three days ashore at Ernestina's office/museum.

The images show our track out of the harbor after a briefing at dockside. On the way out we organized a logistics team to ready a plankton net and gear, stream the taffrail log and prepare for the net deployment. The meter net was streamed at the surface for a run of 2/10 nautical mile. A calculation revealed the volume of water sampled and when the sample came aboard, participants noted the various species including a trumpet fish, ctenophores and spider crab larvae. In addition, there were the crab zoea with extremely long beaks! Biomass and plankton density could be extrapolated.

Other activities on deck included studying the mechanics of the Ernestina windlass with weights, tape measures and spring scales. We discussed static and dynamic friction, mechanical advantage and simple machines. Others were at the chart trying various navigational techniques (as fog and low visibility might allow) A fourth station focused on physical parameters of the water with electronic equipment brought by David Small.

After lunch we set sail back into the harbor with navigation and other discussions taking place on the way back to the dock.
