Ocean Remote Sensing Issues IOGOOS MeetingGrand
Bay, MauritiusNovember 4-9, 2002Report to
IOCCG by

Remote Sensing Applications / Capacity Building
Report
3
Dont duplicate what is already being
undertaken by others

• Build linkages to like programs
• that operate elsewhere

4
Issues

• Data exchange eg TM, ETM, SPOT data problem?
• High spatial and spectral resolution data are
  expensive on scale of IO coastal zone
• What are the choices / preference for satellite
  data sources?
• Hardware and software needs of users
• Climate group needs (we think) are generally well
  met by existing data centers (eg scatterometers /
  altimeters/ SST (?))

5
Issues (continued)

• Linkage between climate group program and
  extension to the coastal ecosystem management
  scale
• Understanding of physical forcing of
  biogeochemical variables
• How do we utilize / integrate remotely sensed
  products into such programs?

6
Science Issues

• Coastal waters (Case 2) emphasis algorithms
  need more work in high sediment regions, shallow
  waters
• Compliance with standards and protocols on data
  products and measurements
• Change detection (mitigation/ degradation) is a
  priority and implies a focus on accurate products
  and QC / QA

7
Planned Actions

• 1 Compile a resources directory on satellites
  and their products appropriate to ocean research
  including- product descriptors- accuracy- spat
  ial and temporal resolution- availability (real
  time, delayed)

8
2 Compile an Inventory of Research Capacity
Building Facilities of IO Regional Centers

• CB facilities / lecture rooms etc
• CB facilities / computing laboratories
• Wet laboratories (eg HPLC)
• Instrumentation calibration / validation
• Cruise capability
• Staff /expertise / specialization
• DB data collection data archive

9
3 Capacity Building Needs

• Science of remote sensing / understanding of
  products and limitations
• Interpretation of products
• Training / software and application
• - Assimilation of RS data into ecosystem models
• - RS Capacity Building applications address
  these using case studies

10
Capacity Building Needs (cont)

• Scatterometry / surface winds
• Altimetry /surface currents / limitations
• Inshore currents / feature tracking
• SST / frontal detection
• Ocean color products (Chl a, suspended sediments,
  dissolved organics, water optical attenuation,
  primary production)
• Processing data from new satellites eg
  (MODIS/MERIS/IRS) - consistency
• New products

11
4 Ocean Information Technology (OIT)

• Work with the Climate and Coastal groups toward
  identification of acceptable OIT system
• Initiate evaluation of OIT system for RS support
  of IOGOOS programs

12
Specific Areas of Focus

• Fisheries applications (prawning)
• Ecosystem status and management
• Soil erosion / sediment transport
• Establishment of regional reference sites

13
Pacific Rim Cruise ?

• Training in in situ sampling and measurement
  protocols (reference sites emphasis)
• Training in the interpretation of satellite
  data products
• Training in regional applications of data

14
2003 Activities

• Fiji meeting to be relocated to Brisbane May /
  June 2003. Finances yet to be resolved!
• IOGOOS follow-up planning meeting tentatively
  scheduled by IOC for Hyderabad in June /July
  2003. Dialogue continuing with with Dr
  Radakrishnan, INCOIS and Chair IOGOOS.
