The advantages of geostationary observations of sediment plumes and phytoplankton blooms have been reported for coastal waters in the southern North Sea and west Pacific. So far, similar observations have not been possible for the Gulf of Mexico where blooms of Trichodesmium erythraeum often occur. Here, using data collected by the Geostationary Operational Environmental Satellite (GOES) Imager...

In this paper, we propose a novel approach to reduce dynamic power in set-associative caches that leverages on a leakage-saving proposal, namely Cache Decay. We thus open the possibility to unify dynamic and leakage management in the same framework. The main intuition is that in a decaying cache, dead lines in a set need not be searched. Thus, rather than trying to predict which cache way holds...

pollutions. Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...

In spring/summer 2015, a toxic bloom by the diatom Pseudo-nitzschia (PN) occurred along the west coast of the United States which led to closures of the harvest of razor clams and Dungeness crabs. Twice monthly observations of temperature, salinity, nutrients, chlorophyll and phytoplankton species composition allowed us to track oceanographic conditions preceding and during the development of t...

The last decade has seen a dramatic increase in the size of western Lake Erie cyanobacteria blooms, renewing concerns over phosphorus loading, a common driver of freshwater productivity. However, there is considerable uncertainty in the phosphorus load-bloom relationship, because of other biophysical factors that influence bloom size, and because the observed bloom size is not necessarily the t...

The first 4 years of SeaWiFS ocean color data (September 1997–August 2001) provide the first synoptic quantification of seasonal and interannual phytoplankton chlorophyll variability in the Gulf of Maine. Climatological monthly means show spatial patterns associated with the annual cycle. Concentrations are elevated throughout the year in coastal regions and over shallow banks (Georges Bank, Na...

Introduction: Bloom filters [1] are a space-efficient, probabilistic data structure for representing a list of elements (for example, a list of strings). A Bloom filter is an array of m bits. A string is mapped into a Bloom filter by inputting it to a group of k hash functions resulting in k array positions. Each indexed array position is set to 1. A string is tested for membership by inputting...
