Definition of Rank

  • Rank 1 is a one-dimensional parameter
  • Rank 2 is a two-dimensional parameter
  • Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

WOCE Bathymetry Screening carried out by BODC

BODC have screened the series header information and the parameter values in the data cycles. Header information has been inspected for irregularities and inconsistencies between related information.

Positions have been checked using a visual inspection on a world map and by calculating platform speed. Time channels have been checked and corrected where appropriate. Duplicate data cycles have been removed.

Data cycles have been visually inspected and compared to ETOPO5 for guidance: Discovery cruises have bathymetry flagged where depth > 1000+ETOPO5. No data values have been altered, values suspected to be dubious have been marked as suspect. Caution documents have been written where appropiate.


Project Information

World Ocean Circulation Experiment (WOCE)

The World Ocean Circulation Experiment (WOCE) was a major international experiment which made measurements and undertook modelling studies of the deep oceans in order to provide a much improved understanding of the role of ocean circulation in changing and ameliorating the Earth's climate.

WOCE had two major goals:

  • Goal 1. To develop models to predict climate and to collect the data necessary to test them.

  • Goal 2. To determine the representativeness of the Goal 1 observations and to deduce cost effective means of determining long-term changes in ocean circulation.
