ATLAS and TRITON in the Indian Ocean

Development of a 47-element multi-platform network designed to support climate forecasting and research. PMEL buoys were first deployed in October 2004 and now is planning several changes to decrease the amount of data lost to vandalism. Two new ATLAS mooring were deployed in the Bay of Bengal in collaboration with INCOIS and MoES

At the present time, 10 surface moorings and four deep equatorial moorings are active.

Near real time data and visualization-tools are available at the PMEL mooring data sites

TRITON In the Indian Ocean

JAMSTEC is operating two moorings in the Eastern Indian Ocean at 95E-5S and 90E-1.5S from October 2001 and an ADCP at 90E - 0

Operational

Distribution through GTS and web page the same as TAO data. The TAO/TRITON data distribution has been started since January 1st, 2000 from TRITON and TAO homepages

Equatorial deep-sea current meter moorings (Indian Department of Ocean Development)

Three mooring are active: location 93-0 since February 2000, at location 83E-0 since December 2000 and at location 76/77E-0 in March 2002. The mooring are augmented with 6 Recording Current Meters (RCMs) at 100 m, 300 m, 500 m, 1000 m, 2000 m and 4000 m. One Up-looking ADCP is placed at 100 m on top of each mooring

MoES is expanding the OOS-moorings with 4 additional ADCP mooring sites across the equator at 77E and 93E in 2008

The time-series currents data can be downloaded at the NIO web site

The current global OceanSites map clearly shows that the Indian Ocean is the least observed basin

IOP is working on recommendations for new sites

LOCO (Long-term Ocean Climate Observations)

Array of moorings, with current meters, ADCP's, T-S sensors, and sediment traps deployed at the narrowest section in the Mozambique Channel. The observations will be used mainly to quantify the variability of the meridional mass and heat transport, to relate this variability to Indian Ocean (or El Nino) climate modes and to study the relation between this variability and the 'downstream' formation of Agulhas Rings

Established 2003. Multiyear project projected to at least 2008

BOB and ASEA buoy networks

The Indian National Data Buoy Programme (NDBP) of the National Institute of Ocean Technology (NIOT) is in charge of collecting oceanographic and meteorological parameters over Indian Seas in order to improve oceanographic services and predictive capability of short term and long term climatic changes as well to increase the understanding on ocean dynamics. The active buoys are in the Arabian Sea (ASEA) and Bay of Bengal (BOB). Air pressure, air temperature, wind, SST, conductivity and surface current are recorded every 3 hours. This enhanced data set will improve quality of the product/ services provided by INCOIS, Hyderabad.

Currently there are about 25 moorings but only 18 active. It is planned to have a network of 40 buoys by 2007. NIOT will be incorporating additional sensors to measure parameters such as net radiation, long wave radiation, rainfall and humidity.

the near-real time data of surface met parameters are available on GTS. It is planned to put the moored buoy data on the NIOT website (www.niot.res.in). Weekly data plots are kept for each variable for each buoy location.
