For their outstanding logistical support in collecting the oceanographic data in this report, we thank crews of the U.S. Coast Guard Cutters White Heath and Marcus Hanna and their captains Michael Frias, Buddy Blackburn, Vernon Shay, Peter Boardman, Richard Foy, Thomas Dickey, and Paul Dupuis. The USGS and the USCG safely conducted more than 90 cruises to deploy and recover hundreds of individual instruments on about 160 separate moorings to obtain this long-term data set. Mike Bothner was chief scientist on the USCG cruises. Fran Lightsom, Mary Hastings, and Ellyn Montgomery processed the time-series data. William Strahle, Marinna Martini, and Jonathan Borden oversaw the preparation and deployment of the physical oceanographic instrumentation. Michael Casso and Rick Rendigs oversaw collection and analysis of the the sediment-trap data. Ben Gutierrez helped in the preparation of version 1 of this report. Dann Blackwood took many of the photographs in this report. Bob Barton, Dann Blackwood, Jon Borden, Michael Casso, Jessica Cote, Ray Davis, Peter Gill, Joe Newell, Carol Parmenter, Andre Ramsey, Rick Rendigs, Steve Ruane, and Richard Signell carried out the work at sea, ashore, and in the laboratory. Rick Rendigs, Dan Blackwood, Larry Ball, Steve Cross, and Ken Parolski aided in the successful recovery of several bottom tripod systems by diving when the primary recovery system failed. Donna Newman and Jennifer Martin did the html coding. Mike Connor, Ken Keay, Wendy Leo, Mike Mickelson, and Andrea Rex provided guidance from MWRA. Neil Ganju and Erin Twomey (USGS) provided helpful reviews of this report. Frank Marachi, captain of the fishing vessel Christopher Andrew, provided assistance and valuable local knowledge on a number of cruises.
