Report on the SNOMS Swire NOCS Ocean Monitoring System. System description and inventory for the MV Pacific Celebes system fitted June 2007

Abstract

The SNOMS project brings together the resources of the United Kingdom’s National Oceanographic Centre, Southampton (one of the world’s leading centres for marine research) and The Swire Group (a major multinational corporation) to make a significant contribution towards improving our understanding of the role of the oceans in controlling concentration of carbon dioxide in the atmosphere and hence the worlds climate. The Swire Group Charitable Trust funded the design, assembly and installation of a scientific data collection system on their ship the MV Pacific Celebes. The system is now providing data from areas where no or little data exists particularly in the Indian Ocean, Red Sea and Mediterranean. It links with and connects on-going observations in the Atlantic. Data from the system supports projects both at NOC and elsewhere including the IOCPP (International Ocean Carbon Coordination Project). In Singapore and Jakarta, in June 2007, NOC installed the first system on the Swire ship the MV Pacific Celebes. This report details the modifications made to the ship prior to installation, the installation on the ships and lists all the equipment sent to the ship. A diary of the installation process is available as NOC Internal Document No. 10*. The 4 main scientific instrument packages and control units aboard the Pacific Celebes are :-
1. In the (engine room) machinery space a stainless steel tank connected to the ships pumped seawater supply containing measuring devices for dissolved carbon dioxide and oxygen, total dissolved gas pressure, temperature and conductivity.
2. In the machinery space an electronics cabinet containing the main data logging, control computer and DC power supplies. This is connected to the instruments in the tank, a temperature sensor mounted on the hull and equipment on the Monkey Island.
3. On the Monkey Island a Stevenson screen box containing sensors measuring humidity, air temperature and atmospheric carbon dioxide content.
4. On the Monkey Island an electronics cabinet containing an Iridium satellite communications modem, two GPS receivers and a data logger.
