Full description

CARS2006 spans the southern 2/3 of the worlds oceans, from 70S to 26N, except in the Atlantic where is reaches only to10N. The six water properties mapped in are temperature (deg C), salinity (PSU), oxygen (ml/litre), nitrate (micromole/litre), silicate (micromole/litre), phosphate (micromole/litre). It comprises historic mean fields and average seasonal cycles, derived from all available historical subsurface ocean property measurements (primarily research vessel instrument casts and autonomous profiling buoys). The mean refers to the long-term average of oxygen in the bottom water at each location. This dataset is a contribution to the CERF Marine Biodiversity Hub.

Statement: BLUElink Ocean Archive (BOA) is the result of collecting together the majority of global high-quality buoy and shipboard deepwater hydrographic cast data. It is built on the NOAA/NODC World Ocean Database, WOCE WHP3, Argo, TAO, CSIRO and NIWA archives, and a number of other sources. BOA is an integral component of the development of the CARS climatologies.The quality control of profile data involves many steps, including: 1.location and depth plausibility check 2.value range checking against 3D global value range tables 3.comparison to global S(T) climatology for outlier detection 4.comparison to existing CARS seasonal estimates (ie residuals testing) for outlier detection 5.ingestion into CARS, and a second level of residuals testing, using a tighter threshold (thresholds are set as a multiple of the mapped RMS of residuals.) 6.examination of resultant CARS fields, especially for bullseyes and structure in the RMS-residuals and seasonal harmonics fields, since these are more sensitive to bad data. Prior to being compared with CARS fields, the profiles are interpolated onto a set of 79 CSIRO Version-3 Standard Depth Levels (CSL3). The component datasets of BOA are stored separately in a range of formats since the nature of these datasets is quite varied. This approach allows easy updating of components (for example, the Argo subset is completely renewed every couple of months.) Where the same data could reside in multiple datasets, those datasets are duplicate cross-checked after any updates (scanning only on the basis of time and location, not the enormous task of searching for duplicated property profiles.)
