COAST 2011 used a modified UV-18A Twin Otter (from CIRPAS). Shown is the twin otter at 100 ft off the deck, flying over the science team that was deployed in a coastal research vessel in Monterey Bay. The team was tasked with obtaining "sea truth" for the aircraft overflight. The inset photo shows two of the three C-AIR instruments (BSI’s BioAIR series) onboard.

The C-OPS profiler, deployed by Dr. Stanford Hooker (NASA) in the Arctic as part of the Malina field campaign. The instrument is shown close to the ice edge to emphasize the ability to sample in optically complex waters, wherein a thin layer of melt water (approximately 1 m thick or less in many instances) significantly influences near-surface optical properties.
High Resolution Hybrid Spectroradiometer for OSPREy

Summit, Greenland. Biospherical SUV-150B High Resolution Spectroradiometer in foreground with GUV behind. This is part of Biospherical's UV network and, along with Barrow, became part of NSF's Arctic Observing Network in 2009.
C-OPS Class instrument measuring light penetration under floating plastic balls in a Los Angeles Reservior.

ICE-Pro, a purpose-built, modified C-OPS for work under the ice, on ICESCAPE 2010. The LuZ/EdZ profiler is the red cylinder on the left. A radiometrically matching Ed0 solar reference is mounted atop the tripod, which also aids in deploying a single-channel reference sensor (QCD-2100) just beneath the ice.
Dr. Karen Frey deploys ICE-Pro, a purpose-built C-OPS for work under the ice on ICESCAPE 2010. The USCGC Healy (background) is fitted with a Biospherical Surface Ocean Reflectance System (BioSORS, S. Hooker/NASA) above-water ocean color monitor on the bow, and a Telescoping Mount for Advanced Solar Technologies (T-MAST) on the bridge, supporting the solar surface reference radiometer.
   
 


BSI Participates in COAST 2011

Print PDF
Three BioAIR instruments—known as the COASTal Airborne In-situ Radiometer (C-AIR) to NASA—flew onboard a modified UV-18A Twin Otter (CIRPAS) in support of the Coastal and Ocean Airborne Science Testbed (COAST) headed by a NASA/ARC team. In addition to C-AIR, a Headwall imaging spectrometer, and the AATS-14 Ames Airborne Tracking Sunphotometer simultaneously collected data over Monterey Bay during the COAST Science Mission.

New Product Announcements

Print PDF
  • OSPREy Systems. OSPREy instruments measure the distribution of light over the spectral range of UV-B to the near-IR, both incident on Earth's surface, and reflected from the ocean.
  • C-OPS: Compact Optical Profiling System. C-OPS instruments measure the vertical distribution of spectral radiance and irradiance in aquatic environments, as well as incident global irradiance above the water's surface.
  • New Profiler for AOPs: C-OPS. The High Resolution Multichannel Profiler is optimized for coastal remote sensing studies. C-OPS is a radiometer system for determining apparent optical properties in aquatic systems. Avoiding any influence from the shadow of the boat, the frame can be optimized for either slow descent rates for work in very shallow (e.g., 3 m) and coastal waters, or faster descent rates for observations in the open ocean.
  • AMOUR. The newly developed Advanced Multi-purpOse Usb Radiometer (AMOUR) is a high-speed USB Radiometer for research and engineering in the laboratory or field.

AOP TM Ready for Download

Print PDF

The NASA Technical Memorandum written by Biospherical and NASA titled, "Advances in Measuring the Apparent Optical Properties (AOPs) of Optically Complex Waters,” NASA TM-2010-215856, is now available for download. This TM documents the Biospherical systems that support both in-air and in-water AOP determinations and describes the development of the Microradiometer and C-OPS, as well as the SHALLO family of instruments. For your convenience, PDFs of individual chapters from this TM have been included on our Web pages that deal with their respective instruments.
