Global Ocean Observing System

Some call it the WOW

goos objectives
GOOS Objectives
  • Specify (space, time, quality) the ocean data needed on a continuing basis
  • Implement an internationally coordinated strategy for ocean data gathering and exchange
  • Facilitate the development of uses and products of these data and encourage their application for the protection of the environment
global observing systems
Global Observing Systems
  • Climate - GCOS
  • Terrestrial - GTOS
  • Ocean – GOOS
  • WWW and GAW (chemical)

Global Observing Systems Information Center www.gosic.org

goos background
GOOS Background

On-going activities (IGOSS from the early 70s, GLOSS from the early 80s, CPR since the 40s, and many more)

POMS – Pilot Ocean Monitoring Study 1979 (SCOR, IOC, JOC for GARP)

WOW suggested at the IOC from mid 1980s to early 1990s

TOGA, WOCE, IGBP – 1980s and 1990s

CCCO’s Ocean Observing System Development Program (OOSDP) in the 1980s (first action plan 1984)

A special OOSD-Panel then produced a plan for An Ocean Observing System for Climate (1995) which formed the basis for initial GOOS activities

goos today
GOOS Today
  • Global Implementation through enhancement of traditional observing systems (SL, drifters etc)
  • Regional planning and Implementation by GOOS Regional Alliances (GRAs)
  • Coastal program planning (COOP)
  • Pilot Projects
    • ARGO
    • GODAE
    • CARBON
    • COOP (RAMP, CAOS, PhytoNet, ---)
  • Strong Reliance on Satellites

data delivery
Data Delivery
  • Surface Drifters (SVP/GTS) – 95%
  • Sea Level - Fast 86%, MSL 76%
  • XBTs (GTS) – roughly 70%
  • ARGO – 95%
  • Moorings (GTS) - Good
observation trends
Observation Trends
  • Drifters (SVP) - up 15% 2001-2003
  • Sea Level
    • FAST - 10 stations added 2003
    • MSL - stable since 1998
  • XBT- Down 27% 1999-2003 0verall

but HDX growing steadily

  • ARGO - Up, up and away
  • Moorings – primary arrays - encouraging

Others - erratic

surface drifter program requirement 1250 by 2005
Surface Drifter Program(Requirement -1250 by 2005)
  • Jan 2002: 1207 overall, 652 SVP/GTS
  • Jan 2003: 1249 “ 714 “

LDX operated at 10%

sea level gloss
Sea Level - GLOSS

Core Network - 290 MSL stations

  • Subsets
    • Ocean Circulation (OC)
    • Long Term Trends
    • Altimeter calibration

Fast Delivery - 142 stations

oc sea level subset
OC Sea level Subset

Pairs of stations

  • Across narrow straits not suitable for altimetry
  • Across wider straits, choke points and basin-sections to measure transport variability of particular interest
  • Along polar coastlines, especially Antarctica, where winter ice precludes altimetry

19 locations (68 possible sites) identified

moorings
