Expendable Bathythermographs (XBTs)
Real-time data from the Global Telecommunications System
This data set includes Expendable bathythermograph data which have been sent, via satellite, from volunteer observing ships (VOS) to receiving stations onshore. From there, the data is placed on the Global Telecommunications System (GTS) and is available worldwide. This data is read from the GTS at four hour intervals and made available here without any quality control procedures having been applied. The spatial domain is global and the temporal domain is from ca. 1999 to the present. Go to data access page.
Near Real-time data with QC flags
This data set is a subset of the GTS database and consists of profiles which were collected aboard vessels using the Shipboard Environmental data Acquisition Software (SEAS). Once the profiles are received by AOML, they are subjected to an automated quality control (QC) process prior to insertion on the GTS. The QC tests that are applied to this data are based on the GTSPP QC protocols. Those profiles which pass the tests are inserted on the GTS. All profiles, regardless of pass/fail are available here, along with the quality flags. The data set is global, but is limited to SEAS vessels and extends from 2003 to the present.

Delayed mode research quality XBTs
AOML serves as the Atlantic ocean data assembly center for upper ocean thermal data. The data is managed as part of the Global Temperature and Salinity Profile Project (GTSPP). This data set is subject to both automated quality control procedures and to visual inspection by scientists. The GTSPP project has been in operation since the early 1990s but AOML has been archiving XBT data in the Atlantic Ocean for over thirty years. The spatial domain is the entire Atlantic Ocean and archive begins in 1967. The data base is updated approximately once per year. Go to data access page.
High Density XBTs
Drifting Buoy trajectories and SST
AOML serves as the home to the Global Drifter Center and Data Assembly Center. More information on surface drifters is available at http://www.aoml.noaa.gov/phod/dac. The drifter database can also be accessed from here. Go to data access page.
Profiling float data
AOML has developed the United States data management procedures for the international ARGO project. The AOML ARGO homepage details AOMLs role and gives links to the international ARGO information pages. Go to ARGO page.
