May 14, 2014 - ESP Update

ESP-1 mooring near the NERACOOS B site indicated a solid positive hit on today's hab array. The estimate of the A. fundyense population calculated from the lab-generated standard curve was 205 cells/L, the highest signal from the ESPs so far this bloom season. That's still low, but consistent with Chris Nash's report of 2 of 3 mice killed from samples near the Isle of Shoals, only 15 nautical miles to the south of ESP-1.

The other two ESPs (in Casco Bay and offshore of Pemiquid Point) have generally continued to show some very weak positives near detection limits (<100 cells/L).

Note that we are gearing up for a ground truth survey next week (May 20-24) that will sample at all 3 ESP mooring sites and also collect samples from stations along 2-3 transects further offshore from the mooring locations.
