The Sargassum Watch System processes satellite data and feeds results to a Web portal, giving decision makers timely information on seaweed location warnings for potential beaching events.
Starting December 2002, the oil industry operating in and around Lake Maracaibo Venezuela suffered a series of accidents (Figure 1). Fires, sinking two barges, rupture pipelines, spills from floating storage transfer stations, malfunctioning extraction platforms led to extensive spills. Local federal Venezuelan government experts directly observed aircraft, helicopter, various surface vessels. The were recorded by official photography video leaking infrastructure, unofficial recordings...
Abstract It has long been observed that oil slicks under sunglint can reverse their optical contrast against nearby oil‐free seawater. Such a phenomenon described through both empirical statistical analysis of the strength and modeled theoretically using critical angle concept. The angle, in this model, is at which image pixels show no or negligible between oiled nonoiled Pixels away from either positive negative pixels. Although concept fully demonstrated published literature, its...
There is a pressing need to assess coastal and estuarine water quality state anomaly events facilitate management, but such hindered by lack of resources conduct frequent ship-based or buoy-based measurements. Here, we established virtual buoy system (VBS) satellite data visualization interpretation assessment. The VBS based on antenna (VAS) that obtains low-level generates higher-level products using both National Aeronautics Space Administration standard algorithms regionally customized in...
In recent decades, the technology used to detect and quantify harmful algal blooms (commonly known as red tides) characterize their physicochemical environment has improved considerably. A remaining challenge is effective delivery of information generated from these advances in a user-friendly way diverse group stakeholders. Based on existing infrastructure, we establish Web-based system for near-real-time tracking tides caused by toxic dinoflagellate Karenia brevis, which annually threatens...
Satellite-derived sea surface temperature (SST) images have had limited applications in near-shore and coastal environments due to inadequate spatial resolution, incorrect geocorrection, or cloud contamination. We developed a practical approach remove these errors using Advanced Very High Resolution Radiometer (AVHRR) MODerate-resolution Imaging Spectroradiometer (MODIS) 1-km resolution data. The objective was improve the accuracy of SST anomaly estimates Florida Keys provide best quality...

Using data collected over the Gulf of Mexico during night between May 2012 and September 2013 by Visible Infrared Imager Radiometer Suite (VIIRS), we demonstrate a new application from its day-and-night band (DNB). Under cloud free moon glint conditions, DNB revealed surface oil slicks natural seeps. This is despite fact that signal-to-noise ratio (SNR) this wide (505–890 nm) under much lower (30:1–50:1) resolution also coarser (750 m) than VIIRS imaging bands (375 daytime solar...
The ANTARES network seeks to understand the variability of coastal environment on a continental scale and local, regional, global factors processes that effect this change. focus are zones South America Caribbean Sea. initial approach includes developing time series in situ satellite-based environmental observations oceanic regions. is constituted by experts seek exchange ideas, develop an infrastructure for mutual logistical knowledge support, link located around Americas with real-time...
