Remote Sensing
• Advantages– Synoptic images
– Global coverage
– High temporal resolution
• Role of oceanographic satellites– Applications in many
disciplines

Moderate Resolution Imaging Spectroradiometer (MODIS) Images
• Sea surface temperature and ocean color data from 2001 to present
• Spatial resolution ~1km2

Sea surface temperature (SST)Advanced Very High Resolution Radiometer
(AVHRR)
• Derived from infrared observations from AVHRR aboard NOAA satellites
• Data for SST are available on a daily basis
• ~1km2 spatial resolution
3 day SST compositeFebruary 19-21, 2005

Sea-viewing Wide Field-of-view Sensor (SeaWiFS)
http://imars.usf.edu/seawifs/index.html
• Ocean color• Aboard SeaStar
satellite• Data for South East
Caribbean Basin, West Florida Shelf, and Intra-Americas Sea
• August 1997-present

Carbon Retention In A Colored Ocean (CARIACO)
• Collaborative program between many institutions that focuses on understanding the link between ocean surface and sinking flux of particulate carbon in the Cariaco Basin
• 12 year monthly time series of oceanic parameters such as pH and TA

Millennium Global Coral Reef Mapping Project
http://www.imars.usf.edu/MC/index.html
• Funded by NASA Oceanography Program
• Goal: characterize and map coral reef systems in Caribbean-Atlantic, Pacific, Indo-Pacific, and Red Sea
• Landsat 7 archive complemented by Landsat 5, ASTER and IKONOS images– Database currently
contains over 1700 Landsat 7 images

#51. Determine research goals and set priorities.
• Calcification rates on a more community vs. organism-based scale (organisms other than corals)
2. Are the existing stations providing the information that we need to answer the questions that we’re asking?
• Should we focus efforts on augmenting the data collected at existing sites and good quality control, versus putting up new sites?
• Coupling ICON with satellite data to enhance spatial resolution.
3. Where should we focus our efforts (location(s))?
4. How do we standardize protocols?
Methods book? Central Sample Analysis Center?
5. Where would be ideal for this sample analysis center – who has the interest and
manpower/$/technology to provide these services?
