The Long Island Sound (LIS) Respire Program
- April/May (2020) cruises are cancelled due to Corona virus
- March (2020) the 10th cruise is completed.
- February 2020, Lauren Barrett presents LIS Respire results at the Ocean Sciences Meeting in San Diego, CA.
- January 11th 2020, Lauren Barrett presents Shell Day results to the Shellfish Commission
- December (2019) The 8th Respire cruise is completed focusing on underway measurements
- November (2019) The 7th Respire cruise with full discreet sampling is completed
- October (2019) The 6th Respire cruise is completed focusing on underway measurements
- Sept (2019) To date 5 research cruises have been completed successfully and sample analyses is underway!
- August (2019) The project joins the National Shell Day event as Connecticut’s alkalinity analysis center.
- June (2019) Initial sampling cruise begins!
- May (2011) The project’s Quality Assurance Plan has been approved by the Environmental Protection Agency and research is now underway.
|1)To measure respiration rates and biological oxygen demand (BOD) at 10 Long Island Sound (LIS) water quality stations over the project period.
2)To measure key biogeochemical parameters at these stations (pCO2 and total alkalinity (TA)), in addition to those already measured in the LIS surveys (pH, nutrients, dissolved oxygen (DO), chlorophyll a and organic carbon).
3)To conduct incubations on dissolved and particulate organic carbon (DOC, POC) that measure degradation rates at 10 sites across LIS to complement respiration studies.
4)To evaluate the above values across LIS spatially and temporally to begin the foundational work for a combined LIS biogeochemical model that considers respiration in terms of season (i.e. temperature (T), salinity (S), stratification), location, depth, DOC and POC lability and important biogeochemical parameters.
5)To conduct a LIS DO balance for LIS from 1991 to present.
6)To ascertain the utility of adding respiration and/or inorganic carbon components to the Long Island Sound Water Quality Monitoring Program.
