SOT IV SOOPIP Chair Report Program Review Steven Cook
Terms of Reference a)Review, recommend on and, as necessary, coordinate the implementation of specialized shipboard instrumentation and observing practices dedicated to temperature and salinity measurements; b)Coordinate the exchange of technical information on relevant oceanographic equipment and expendables, development, functionality, reliability and accuracy, and survey new developments in instrumentation technology and recommended practices; c)Ensure the distribution of available programme resources to ships to meet the agreed sampling strategy in the most efficient way; d)Ensure the transmission of data in real time from participating ships; ensure that delayed mode data are checked and distributed in a timely manner to data processing centres; e)Maintain, through the SOT Coordinator, appropriate inventories, monitoring reports and analyses, performance indicators and information exchange facilities; f)Provide guidance to the coordinator in supporting the SOOP; g)Prepare annually a report on the status of SOOP operations, data availability and data quality
Current SOOPIP Members Australia Canada France (IRD Brest and Noumea) Germany India Japan Mediterranean Forecasting System Pilot Project (MFSPP) United Kingdom USA (AOML and Scripps IO) Not active 2005 or 2006 –Russian Federation –China
Real-Time XBT Transmissions
XBT Decline Issues Implementation of ARGO. –Traditional hard to sample areas are now better sampled (i.e. Southern Ocean, G. of Guinea). ~ 25% of FRX & HDX Lines not sampled. ~ 33% of FRX & HDX Lines under sampled. Fewer observations but better quality?
Item: IV/1.1.5 XBT Community to review and comment to the SOOPIP Chair on the Japanese papers comparing TSK and Sippican T-5 probes regarding possible changes to the fall rate equations. Status?
Item: IV/2.2.2 & IV/2.3.1 Efforts to be renewed to recruit ships on the following lines: –IRD same coverage on AX01,AX05, AX11, AX15 & AX20. –NOAA initiated coverage on AX34 + Drifters. –SIO initiated/modified IX15 & IX21 –SIO PX06/PX31 changed from PX06/PX09. –SIO replaced PX50 with PX08. –BSH changed ships on AX11. –Japan searching for ship on IX06.
Item: IV/4.1.1 Operators to send XBT sampling plans for each route maintained to TC and Chair. –IRD same level as –JAMSTEC/JMA ceased sampling on PX05 but continued on IX09(N)/IX10(E) & PX40. –OOPC to review N-S vs. E-W line assignment vs. required horizontal resolution.
Since 1990 the global Low Density XBT network has been monitored and coordinated in an effort to more effectively utilize resources and improve sampling, data transmission and processing. National XBT programs evolved over the years to adapt to a changing maritime industry. Today, maritime shipping has evolved to the point that it now emulates the airline industry. To be competitive they must endeavour to keep their ships fully loaded and underway. As the maritime industry becomes more competitive larger companies are buying up smaller companies in an effort to become more efficient in dealing with their cargo demands. The SOOPIP community finds itself burdened with vessels coming and going offline at ever increasing frequency and usually with very little notice. Ships are staffed by fewer and fewer people and the time spent in port is becoming less and less. This means less opportunity for our programs to interact with shipboard personal, install equipment and train operators. Additionally, while at sea ships personnel have less time to devote to our sampling requirements. Placing ship riders on board to collect quality data is becoming more the norm than in the past when we depended almost totally on ships personnel. The burden is on us to continually recruit new vessels and shore side support assistance with the shipping of our equipment and with the installing and de-installing of equipment. There is an enormous amount of scientific/maritime industry experience in the SOOPIP community. Therefore the SOOPIP is invited to discuss these problems and express their collective thoughts concerning just what routes can be realistically maintained.
Lines not Sampled in 2005 AX-15PX-11 AX-25PX-21 IX-06PX-35 IX-07PX-36 IX-08PX-81 IX-09S
