MapServer WFS The Marine Geoscience Data System (MGDS is a digital data repository and metadata catalog. Its data resources support scientists working broadly on solid earth science problems ranging from mid-ocean ridge, subduction zone and hotspot processes, to geohazards, continental margin evolution, sediment transport at glaciated and unglaciated margins and interdisciplinary science in the Southern Ocean. The Marine Geoscience Data System hosts primarily marine geoscience data from the seafloor and subseafloor acquired with ships, towed platforms and submersibles and includes both derived data products and supporting field data. Primary data types include bathymetry, sidescan sonar, near-bottom photos, and active source seismic data, as well as a diverse array of other long-tail sensor data (e.g. in-situ temperature and chemical probes, optical backscatter). This Web Feature Service provides access to data acquisition event information including stations, launches (dives), and survey lines. http://www.marine-geo.org/services/mapserver/eventwfs?
