The global distribution pattern of coccolithophorid blooms was mapped in order to ascertain the prevalence these world's oceans and estimate their worldwide production CaCO 3 dimethyl sulfide (DMS). Mapping accomplished by classifying pixels 5‐day composites coastal zone color scanner imagery into bloom nonbloom classes using a supervised, multispectral classification scheme.

The causative agent of cholera, Vibrio cholerae , has been shown to be autochthonous riverine, estuarine, and coastal waters along with its host, the copepod, a significant member zooplankton community. Temperature, salinity, rainfall plankton have proven important factors in ecology V. influencing transmission disease those regions world where human population relies on untreated water as source drinking water.

Carbonates are the largest reservoirs of carbon on Earth. From mid‐Mesozoic time, biologically catalyzed precipitation calcium carbonates by pelagic phytoplankton has been primarily due to production calcite coccolithophorids. In this paper we address physical and chemical processes that select for coccolithophorid blooms detected in Sea‐viewing Wide Field‐of‐view Sensor (SeaWiFS) ocean color imagery. Our primary goal is develop both diagnostic prognostic models represent spatial temporal...
This report introduces Q EPCAD , B, a program for computing with real algebraic sets using cylindrical decomposition (CAD). QEPCAD B both extends and improves upon the system quantifier elimination by partial written Hoon Hong in early 1990s. paper briefly discusses some of improvements implementation CAD via CAD, provides somewhat more detail on extensions to that go beyond elimination. The author is responsible most extended features but basic SACLIB library which based are results many...

The concept of phytoplankton functional types has emerged as a useful approach to classifying phytoplankton. It finds many applications in addressing some serious contemporary issues facing science and society. Its use is not without challenges, however. As noted earlier, there no universally-accepted set types, and the used have to be carefully selected suit particular problem being addressed. important that sum total all matches all phytoplankton under consideration. For example, if...
Coccolithophores are one of the most abundant eukaryotic phytoplankton in oceans and distinguished by their ability to build calcitic platelets (coccoliths). Of numerous species, Emiliania huxleyi is considered major calcifiers pelagic ocean. There growing concern that increasing levels CO2 atmosphere subsequent acidification ocean may disrupt production coccoliths. Furthermore, any change global distribution abundance E. relative non-calcifying groups (e.g. diatoms) will have important...
Ocean ecosystems are subject to a multitude of stressors including changes in ocean physics and biogeochemistry, direct anthropogenic influences. Implementation protective adaptive measures for requires combination observations with analysis prediction tools. These can guide assessments the current state, elucidate ongoing trends shifts, anticipate impacts climate change management policies. Analysis tools defined here as circulation models that coupled biogeochemical or ecological models....

This paper has two parts. In the first part we give a simple and constructive proof that quantifier elimination in real algebra is doubly exponential, even when there only one free variable all polynomials quantified input are linear. The general result not new, but hope explicit nature of makes it interesting. second uses construction to prove some results on effects projection order CAD -- roughly problems for which produces constant number cells another exponential cells, orders produce...

Abstract. Coccolithophores are the primary oceanic phytoplankton responsible for production of calcium carbonate (CaCO3). These climatically important plankton play a key role in carbon cycle as major contributor to open ocean pump (~50%) and their calcification can affect atmosphere-to-ocean (air-sea) uptake dioxide (CO2) through increasing seawater partial pressure CO2 (pCO2). Here we document variations areal extent surface blooms globally coccolithophore, Emiliania huxleyi, North...
