The Harbor SEALs completed their 2nd day of monitoring of the Upper Hudson River Estuary. Team work was in full display as the SEALs worked in subfreezing temperature. The data is available for the public here. Once the samples are taken, students quickly measure the dissolved oxygen using the Azide modification of the Winkler method, measure temperature, and enterococcus bacteria. It is quite a scene to watch the level of intensity the students obtain on a given sampling day. For more images of the SEALs at work click here.

On another note, congratulations to the winners of the invertebrate larvae identification contest. 10th graders Tahirah and Nicolle successfully identified the nauplius larvae as pertaining to a barnacle.
