Image Processing Facilities
Current research at the Bio-Optical Oceanography Laboratory includes image processing and analysis of satellite and airborne data including: SeaWiFS, AVHRR, AVIRIS, MODIS, ETM+, AISA, IKONOS, and Hyperion. Our research facility includes a new laboratory and conference area with a computer laboratory for graduate students. The research and teaching computers are equipped with: ENVI, ArcGIS, Origin, SeaDas and MatLab.
The Boriken is a 21.5' Privateer that has been customized for the needs of coastal bio-optical measurements. It has two outboard Yamaha 85 hp engines, two portable generators (1 and 2 KW), and two davits with hand winches.
AUV of the BIO-OPTICAL OCEANOGRAPHY LABORATORY at UPRM
A new Seabed-type Autonomous Underwater Vehicle (AUV) was delivered in December 2009 to the Bio-optical Oceanography Laboratory and initialy tested at Isla Magueyes in La Parguera. The AUV was developed by Dr. Hanumant Singh from the Woods Hole Oceanographic Institution. This vehicle was built with funding from NSF's MRI Program for optical ans acoustic imaging of shallow and mesophotic coral reefs in Puerto Rico and the U.S. Virgin Islands. The main imaging sensors are a Delta-T multi-beam sonar and two high-dynamic range color cameras. High definition video and fluorescence imaging capabilities will be added in 2010.
Tech Specs of the UPRM AUV
Seabotix Remote Operated Vehicle (ROV)
This ROV has a depth range of 150 meters and its equipped with two video cameras, artificial lighting and a three jaw grabber. We use the ROV to supplement the AUV surveys in areas of vertical walls and high slopes.
Satlantic HyperPro Profiler
This instrument measures irradiance and radiance profiles with a spectral range of 350-800 nm. We derive spectral attenuation coefficients from these data to calculate the amount of light reaching benthic communities and to charactherize water optical properties. The system includes a backscattering meter and a chlorophyll fluorometer.
