Abbie Harris - NOAA Ocean Acidification Think Tank #5

Outline

• IMaRS products and results– Sea Surface temperature – MODIS– SeaWiFS– CARIACO– Millenium Global Coral

Reef Mapping Project

• Future research

Antenna at USF College of Marine Science


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

High resolution MODIS image for Cayman Islands

QuickTime™ and aTIFF (Uncompressed) decompressorare needed to see this picture.


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


Degree Heating Week (DHW)

• Sea surface temperature• AVHRR

• MODIS

Degree Heating WeekSeptember, 2007


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


Millennium Global Coral Reef Mapping Project

• Applications – Comparative

geochemical, biological, and geological studies

– Modeling

– Monitoring and planning

Education and Outreach

• Resources for students, teachers, researchers

• Information about ocean science, research methods, careers

• SCUBAnauts


Future Research

• Continued development of Millennium applications• Development, refinement, and application of remote

sensing techniques– Circulation patterns– Ocean color– SST– River plume dispersal patterns– Upwelling– Changes in reef environments


Future Research

• Ocean acidification and CaCO3 production

on reefs

– In situ • ICON

• Field samples

– Remote sensing• Scaling up in situ measurements


NOAA - Think Tank

#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?
