Climate: A Database of Temperature and Salinity Observations for the Northwest Atlantic
By Gregory, D.N.
Abstract
The Ocean Science hydrographic database (Climate) is a comprehensive, open access collection of temperature and salinity data for the Northwest Atlantic and Eastern Arctic, an area defined by 35°N - 80°N and 42°W
- 100° W. The data come from a variety of sources including hydrographic bottles, CTD casts, profiling floats, spatially and temporally averaged Batfish tows, and expendable, digital or mechanical bathythermographs. Near real-time observations of temperature and salinity from the Global Telecommunications System (GTS) are also included. The database currently consists of approximately 630,000 profiles and 30 million individual observations from 1910 to the present. Vertical resolution varies from 1 m (for CTDs) to ~ 10-100 m for traditional bottle casts. Climate is updated monthly and approximately 20,000 new profiles are added each year.
The database can be accessed at the web address:
