During March 12, 2008 a bio-optical sampling in Mayagüez Bay was carried out as a teaching experience of the graduate course CMOF 8446 (Oceanographic Remote Sensing II), given by Dr. Roy Armstrong in the Department of Marine Sciences. The students had the opportunity to deploy the bio-optical rosette, make measurements with the GER-1500 spectroradiometer, and…
Ocean color of Mayaguez Bay has been part of the research efforts made by the GERS Lab since its foundation. In most recent years the work has focused on testing and validating the MODIS sensor. The results of such work were presented during this year NOAA-CREST Symposium that was held in the University of Puerto…
The hyperspectral sensor AISA flew over Puerto Rico during December 2007. This first-time ever mission, coordinated by the UPRM CenSSIS project (a NSF project), involved multiple research groups that sampled on sea and land. GERS Lab collaborated with the Bio-optical Oceanography Lab to measured the bio-optical properties on different sites over La Parguera Reefs and…
Jose Martinez and Natlee Hernandez presented their undergraduate research to the Geology faculty in November 30, 2007. Jose continued his efforts toward generating a site-specific algorithm for the estimation of suspended sediments and Natlee validated the Chlorophyll-a product provided by MODIS and NASA-standard algorithms, both works in Mayaguez Bay. These projects are part of the research…
Fernando Gilbes presented the work entitled “Developing a protocol to use remote sensing as a cost effective tool to monitor contamination of mangrove wetlands” during the Annual Symposium of the Department of Natural and Environmental Resources (DNER) in October 25, 2007. This project is sponsored by the Sea Grant Program and other authors of the…
In order to apply remote sensing to coral reef studies it is necessary to understand the bio-optical variability of the water column. This is the main objective of the most recent work by the GERS Lab in collaboration with Dr. Roy Armstrong, Director of the Bio-Optical Oceanography Laboratory (BIOL) of the UPRM-Department of Marine Sciences.…
Multiple studies have been performed in La Parguera Bioluminescence Bay, but none of them have measured the in situ bio-optical properties until now. As part of Deborah Cedeño Ph.D. dissertation project (a graduate student of the UPRM-Department of Marine Sciences), we used the GERS Lab Bio-Optical Package to measure these properties in the field during…
As part of the NOAA CREST project a different sampling design was performed in Mayaguez Bay to better understand the spatial variability of bio-optical properties. On May 2 of 2007, the bio-optical package was lying down on deck and connected to the water intake of the R/V Sultana. Seawater from the surface flowed continuously through…
The Bernard M. Gordon Center for Subsurface Sensing and Imaging Systems (CenSSIS) held its two-day,Year Seven National Science Foundation Site Visit on April 19-20, 2007 in Boston, MA. During this activity our graduate student Carmen Zayas-Santiago, from the Department of Marine Sciences, presented the poster titled “Spectral Libraries of Submerged Biotopes for Benthic Mapping in…
Belyneth Deliz, Almaris Martinez, and Augustine Roman (all undergraduate students) carried out leave reflectance measurements in the field as part of our Sea Grant project. They also collected leave and sediment samples for metal analyses in the Atomic Absorption Spectrometer (AAS) laboratory of Dr. Arturo Massol, in the Biology Department at UPRM.
