CREST has focused on developing measurement techniques and algorithms to improve retrievals of inherent optical properties (IOPs) coastal waters for assessments of water quality needed for effective response and planning. That included hyperspectral field measurements, in and above water reflectance and comparisons with satellite data and radiative transfer simulations using Hydrolight, examining the effects of atmospheric corrections. Promising improvements in retrieval techniques have been demonstrated: notably near IR algorithms (less susceptible to spectral interference) for Chl retrievals and harmful algal blooms (HABs) detection in coastal waters, neural network (NN) approach for IOP retrievals and harmful algal blooms (HABs) detection. These approaches will now be coupled with modeling techniques to arrive at effective coastal water IOP and constituent retrievals, identification and tracking of HABs and other trace contaminants in coastal and estuarine waters. An important new impetus comes as a result the Long Island Coastal Observatory (LISCO) in Long Island Sound very recently established by CREST. This new facility dedicated to coastal studies, combines a multispectral.
SeaPRISM radiometer, which is part of the NASA Aeronet network, and a hyperspectral HyperSAS radiometer and now plays an important role in the validation of current and future Ocean Color satellites as well as atmospheric corrections for coastal environments and time series characterization of coastal waters of interest to climate change. Long Island Sound will be also used as a test bed for the development of the hydrodynamic model combined with remote sensing data, which will have predicting
capabilities for water quality and eventually for Ocean Health.
Mapping to NOAA and NESDIS Strategic Plans
This theme addresses NOAA Mission goals and objectives: Healthy Oceans, Resilient Coastal Communities and Economies, Comprehensive Ocean and Coastal Planning and Management, Improved
Coastal Water Quality supporting human health and coastal ecosystems. It is also related to NESDIS goals to Protect, Restore, and Manage the Use of Coastal and Ocean Resources through an Ecosystem Approach to Management and to Serve Society’s Needs for Weather and Water Information.
