Data collected by OMG using the probes, the radar and other means are all freely available to anyone by visiting the Physical Oceanography DAAC (PO.DAAC). These data have already been used in many important discoveries by scientists and are also of wide interest to people in Greenland and beyond. See the following article to learn more.
Bathymetry
The bathymetry survey was primarily conducted using multi-swath Multibeam Echo Sounder System (MBES) equipment and procedures. MBES uses a sonar that produces an angular swath of beams to the port and starboard side in a single ping to effectively map a corridor with a width approximately 3-4 times the water depth. In addition to the multibeam echosounder, several more instruments are required on the vessel to georeference the raw multibeam data into corrected soundings. A GPS installed on the vessel is used to accurately position the location of the multibeam. Data from a pitch, roll, heave and heading sensor is used to correct the raw sounding based on the vessels attitude at the time the sonar ping. The sound velocity of the water column is required to convert the soundings from raw time-of-flight measurements to a corrected range as well as correct the sounding for refraction as it passes through the water column. Additional bathymetry data was collected by a smaller vessel usin …
