Exchange moorings at two locations and collect sediment cores at two long-term monitoring stations. We made measurements of oxygen profiles at the sediment stations. Water samples were collected for total suspended matter measurements at the surface and bottom at Station 3.
Location
Massachusetts Bay, Massachusetts, United States, North America, North Atlantic,
Summary
Divers were not needed. All moorings were recovered without incident. K. von der Heydt tested the radio modem from the ship to a tower near Marshfield. Moorings recovered: 4 (#540, 541, 542 and 543 all deployed FA 98044 MARCUS HANNA Sep. 30 - Oct. 1, 1998). Moorings deployed: 4 (#551, 552 and 553, all recovered FA 99008 MARCUS HANNA May 11-12, 1999; #554 recovered FA 99040 CHRISTOPHER ANDREW May 26, 1999).
