SUBJECTS
Science Information By:
Through its lead role in GTSPP, MEDS has significantly improved handling efficiency and data quality for Canadian data by applying the technology developed in the project. MEDS annually processes and archives over 60,000 oceanographic profiles reported for the world oceans in near real-time into the Ocean Profiles databases through this program. MEDS also supports GTSPP activities of the Ship of Opportunity Programme Implementation Panel (SOOPIP) and the WOCE Upper Ocean Thermal Program (WOCE_UOT).
To assist in the real-time data flow, MEDS reports monthly on the data that it received via its links to the Global Telecommunications System (GTS).
- International GTS/GTSPP (PREINT) report
- Advisory to users of ISDM real-time BATHY/TESAC data.
SHIP49 Identifiers
Between the years 1995 to 2000, more than 20 thousand BATHY coded messages were received from Japanese sources with no valid call sign, and no time of day. A decision was made to keep these data despite the lack of a valid time, because of the volume of the data set. All of these stations were arbitrarily assigned a station time of 19:00.
SEAS data with wrong dates
Between the years 1994 to 2005, the U.S. VOS SEAS program generated a significant number of profiles with incorrect observation dates. There is no reliable way to distinguish these stations in MEDS archives. The U.S. NODC is currently working to revise the observation dates for the delayed mode version of these data.
Argo data as TESACs
The U.S. Argo program , from 1997 to February 22, 2001, transmitted TESAC messages with pressure values instead of depths. Users are advised that this may not be the sole source of this problem, and the GODAE server should be consulted for the delayed mode version where available.
