Brrr! Snow doesn’t stop the Harris Lab from Sampling in Jamaica Bay.

The snow and cold temperatures didn’t stop our lab from sampling in Jamaica Bay this week.  The Harris Lab is working with the New York City Department of Environmental Protection to examine the effects of wastewater treatment plant upgrades on phytoplankton activity. Besides measurements in the field, we also take water samples back to the lab.

These water samples sit in bottles for 24 hours with different levels of light shining on them in a cold room.  The cold room lets us maintain the temperatures that we see out in the river. We use these samples to measure rates of photosynthesis (making oxygen) and respiration (consuming oxygen) in the water column.
