Summary for Field Activity Number 2004-026-FA

Alternate Leg ID: MH45-04

Area of Operations: Massachusetts Bay, Massachusetts, United States, North America, North Atlantic

Dates: May 19, 2004 to May 20, 2004

Objectives: Exchange long-term moorings, collect sediment cores, obtain oxygen profiles within surface sediment, collect horse mussels using SCUBA from rocky bottoms near outfall, and deploy benthic chambers to measure fluxes of dissolved constituents in sediment-pore waters.

Type of Activity: Sampling
Mooring work

Information to be derived: Time series data
Samples and Chemical Analysis
Grain size analysis
Suspended Sediment Concentrations
Oxygen profiles fluxes of dissolved constituents in pore waters

Summary: Moorings recovered: 2 (#755 and 756 deployed FA 04016 MARCUS HANNA Feb. 5-6, 2004). Moorings deployed: 3 (#766, 767 and 768 all recovered FA 04032 ABBIE BURGESS Sep. 22-23, 2004). All moorings were successfully replaced. Time series sediment trap did not rotate. Slow corer worked perfectly 8 for 8. Oxygen profiler used 2X at Station 3 and 1X at Station 2. Two benthic chambers deployed at Station 3. Divers (Dann Blackwood and Michael Casso) collected 10 horse mussels and a few brachiopods and one boulder covered with coraline algae and other organisms at MWRA Station T4-4.
