Soil climate and atmospheric data for Scott Base, Marble Point, Mount Fleming, Bull Pass, Granite Harbour, Minna Bluff and the Victoria Valley, Antarctica
Abstract:
In collaboration with the United States Department of Agriculture (USDA) climate stations were installed at six locations in the Ross Sea Region including Scott Base, Marble Point and Bull Pass all in the summer of 1998-1999, Mount Fleming in 2001-2002, Granite Harbour in 2002-2003 and Minna Bluff in 2002-2003. These stations make continuous atmospheric and soil climate recordings to provide ... information for comparison of soil climatic attributes with those from Arctic regions, to help understand the impacts of global climate changes on cold region soils and permafrost. New Zealand took over the annual maintenance and data collection from climate stations in the Victoria Valley in the 2001-2002. Each station monitors soil moisture, soil temperature and salinity to depths of 1.2 m. Measurements of atmospheric variables include air temperature, relative humidity, solar radiation and wind speed and direction. MRC temperature probes were installed at depths of 2 cm to 1.2 m at Minna Bluff and Granite Harbour (2002-2003). Measurements are made at 20 minute intervals and averaged and recorded every hour.
Quality
ATTRIBUTE ACCURACY REPORT: The data has been in use by the agency and other agencies since its inception. The database has undergone rigorous quality checks.
HORIZONTAL POSITIONAL ACCURACY REPORT: Used Differential GPS. Data is truncated to 2nd decimal point (about 1500 meters) with respect to location due to confidentiality.

Users must recognize that the analysis and interpretation of data requires background knowledge and expertise about marine biodiversity (including ecosystems and taxonomy). Users should be aware of possible errors in the use of species names, geo-referencing, data handing and mapping. They should crosscheck their results for possible errors, and qualify their interpretation of any results accordingly. Appropriate caution is thus necessary in the interpretation of results derived from OBIS-USA.
Use Constraints
Prior to use of these records in any analysis or report, MARMAP must be notified and if used the provenance of the original data must be acknowledged. Acknowledge the use of specific records from contributing MARMAP databases and acknowledge the use of the OBIS-USA facility. Recognize the limitations of data in OBIS-USA.
