  • Description:
    A summary of Pacific SEAMAP bathymetric, magnetic, and gravity data, collected in the North Central Pacific between 1961 and 1970 by the Coast and Geodetic Survey, and reformated and evaluated by the Marine Sciences Institute of the University of Connecticut, is presented. More than 250,000 values are evaluated as reliable. Of these, more than 150,000 are bathymetric values with an uncertainty of ±10 meters in areas of flat bottom and higher uncertainties in areas of steep slopes. More than 80,000 are total magnetic anomaly values with an uncertainty of ±32 gammas. More than 20,000 are free-air gravity anomaly values with an uncertainty of ±4 mgals. Evaluations were based on consistency of data along ship tracklines, on analyses of misties at trackline intersections, andon contourability of the data. Thoroughness of survey procedures and deletion of measure- ments considered unreliable contributed to thehigh quality of evaluated data.
