Compact Optical Profiling System (C-OPS)

The C-OPS instrument is a culmination of several new technologies, each focused on different aspects of resolving the optical complexity of the near-shore water column. Although C-OPS represents a significant improvement over legacy profilers, it was designed from inception specifically to operate in shallow coastal waters and from a wide variety of platforms ranging from offshore towers, small boats, and ocean-class research vessels. Electronically, the system is self-organizing; when initially powered, the aggregator queries each instrument to determine the optimal power required for operation over the existing length of the cables and the population of detectors available to the configuration.

Geostationary Ocean Color Imager (GOCI)

The Geostationary Ocean Color Imager (GOCI) is one of the three payloads onboard the Communication, Ocean and Meteorological Satellite (COMS). It acquires data in 8 spectral bands (6 visible, 2 NIR) with a spatial resolution of about 500 m over the Korean sea. The ocean data products that can be derived from the measurements are mainly the chlorophyll concentration, the optical diffuse attenuation coefficients, the concentration of dissolved organic material or yellow substance, and the concentration of suspended particles in the near-surface zone of the sea. In operational oceanography, satellite derived data products are used in conjunction with numerical models and in situ measurements to provide forecasting and now casting of the ocean state. Such information is of genuine interest for many categories of users.

Hawkeye

The Hawkeye instrument, flown onboard the SeaHawk CubeSat, is optimized to provide high quality, high resolution imagery (120 meter) of the open ocean, coastal zones, lakes, estuaries and land features. This ability provides a valuable complement to the lower resolution measurements from previous missions like SeaWiFS, MODIS and VIIRS. The SeaHawk CubeSat mission is a partnership between NASA and the University of North Carolina, Wilmington (UNCW), Cloudland Instruments and AAC-Clyde Space and is funded by the Moore Foundation under a grant for the Sustained Ocean Color Observations with Nanosatellites (SOCON).

Moderate Resolution Imaging Spectroradiometer (MODIS)

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

Ocean Land and Colour Instrument (OLCI)

The Ocean and Land Colour Instrument (OLCI) is the successor to ENVISAT's Medium Resolution Imaging Spectrometer (MERIS) having additional spectral channels, different camera arrangements and simplified on-board processing. The OLCI is a push-broom instrument with five camera modules sharing the field of view. The field of view of the five cameras is arranged in a fan-shaped configuration in the vertical plane, perpendicular to the platform velocity.

Optical Sensors for Planetary Radiance Energy (OSPREy)

An Optical Sensors for Planetary Radiance Energy (OSPREy) system consists of radiance radiometers mounted on computer-controlled pointing systems and irradiance radiometers equipped with shadowbands. Synchronous and asynchronous sampling modes measure the sea, Sun, and sky, across a wide spectral range---the ultraviolet (UV), through the visible (VIS) and near-infrared (NIR), and into the short-wave infrared (SWIR)---to derive an unprecedented number of near-simultaneous atmospheric and oceanic parameters. This new sampling capability is designed to provide vicarious calibration and algorithm validation capabilities which will also improve the following: a) the atmospheric correction of ocean color data, b) the accuracy in separating the living and nonliving components of seawater, c) the derivation of water-leaving radiances and associated data products in optically complex (coastal) waters, and d) the understanding of the interaction between the ocean and atmosphere.

SeaHawk

The SeaHawk-1, a 3U CubeSat with HawkEye Ocean Color Sensors, is a partnership between NASA and the University of North Carolina, Wilmington (UNCW), Cloudland Instruments, and AAC-Clyde Space and is funded by the Moore Foundation under a grant for the Sustained Ocean Color Observations with Nanosatellites (SOCON). The aim of the project is to observe the changing biology of the ocean surface. Seahawk was launched in 2018 and is operated from AAC Clyde Space’s Glasgow Operations Centre, with instrument data downloaded to NASA Wallops facility, through the satellite’s X-band downlink. The data is integrated into NASA’s SeaWiFS Data Analysis System and distributed worldwide by the NASA Ocean Biology Distributed Active Archive Center. The data gathered by SeaHawk will enable greater understanding of the marine food chain, oceanic climate, fisheries and pollution phenomena. This information will be vital to our ability to monitor and support the health and sustainability of our oceans.

        Sustained Ocean Color Observations using Nanosatellites (SOCON)

        SOCON is a proof-of-concept project to demonstrate the capability to construct low-cost autonomous nanosatellites – a.k.a. CubeSats – capable of producing high-resolution ocean color imagery. Its first spacecraft, SeaHawk, is only 10 cm x 10 cm x 30 cm (less than 4 in x 4 in x 12 in) in size and weighs less than 5 kg (11 lbs)! Funded by the Gordon and Betty Moore Foundation and led by University of North Carolina Wilmington, HawkEye data will be distributed through a free and open data distribution policy on NASA's OceanColor Web. In addition, SeaDAS software will be modified and made available for HawkEye image processing, display and analysis. SOCON's ultimate goal is to develop a constellation of SeaHawks that provide global measurements of ocean color. Such observations are essential to monitor the health of our living ocean and its ability to sustain important fisheries
