USGS-CMG time-series data: MBAY_LT - 470 - 4701spd-a_d1

USGS-CMG time-series data from the Long-term observations in Massachusetts Bay; Site A-Boston Harbor project, mooring 470 and package 4701spd-a_d1. Measurements of currents and other oceanographic properties were made to assess the impact of sewage discharge from the proposed outfall site.
