The National Oceans and Coastal Information Management System (OCIMS) of South Africa is a large, integrated IT system for enhancing oceans, coastal and maritime governance, and supporting sustainable...
Estimation of methanogenesis by quantification of coenzyme F430 in marine sediments
methane hydrate methanogens function-specific compound analysis marine sedimen
2017/4/10
Coenzyme F430 is the hydrocorphinoid nickel complex which acts as active site in methyl-coenzyme M reductase
(MCR). The MCR-F430 complex catalyzes the last step of methanogenesis: reduction of methyl...
Ecological subsidies alter the structure of marine communities
subsidies alter marine communities
2015/12/16
Subsidies are usually the subject of
purely economic debates. They
represent flow of resources from
one economic sector to another
and can be fundamental to competitive
ability of industries in d...
Designing marine reserve networks for both conservation and fisheries management

2015/12/11
Marine protected areas (MPAs) that excludefishing have been shown repeatedly to enhance the abundance, size, and diversity of species.
These benefits, however, mean little to most marine ...
Marine reserves help preserve genetic diversity after impacts derived from climate variability: Lessons from the pink abalone in Baja California
Marine reserve Overfishing
2015/12/11
Genetic diversity is crucial for the adaptation of exploited species like the pink abalone
(Haliotis corrugata), faced with threats from climate change, overfishing and impacts
associated with aquac...

aerosol optical depth aerosol particle size-distributions aerosol radiative properties direct aerosol radiative forcing
2015/9/16
An overall number of 447 spectral series of aerosol optical depth were determined in the 0.4-3.7 mm wavelength
range by examining the IR-RAD sun-radiometer measurements carried out at Sagres (Portuga...
The Secret Life of Marine Mammals: Novel Tools for Studying Their Behavior and Biology at Sea
Marine Mammals Behavior and Biology
2015/8/19
Given the interest by both the lay and scientific communities, it is surprising how little is known about the open ocean ecology of marine mammals. Their patchy distribution and low abundance leads to...
Carl Wunsch has written a compelling and important editorial in Science (15 Jan 93, p. 296–297), "Marine Sciences in the Coming Decades," which is based on a 1992 study by the Ocean Studies Board of t...
The addition of molecular genetic tools to oceanographic toolboxes began with a pronounced emphasis on ribosomal RNAs (rRNAs). Already these molecules have been used to detect and examine the abundanc...
The last 10–15 years have seen major changes in our views of marine planktonic food webs, primarily from the realization that prokaryotic microorganisms and small eukaryotes are responsible for a sign...
The concept that ocean fronts are important features in oceanic biology has a long history, as noted by the quotations cited above. The example of a functional understanding of fronts provided by a co...
Biological Considerations in Marine Enclosure Experiments: Challenges and Revelations
Estuary system biological disciplines
2015/8/17
Logistical considerations have usually dictated that components of estuarine systems be considered in isolation from one another whether in the laboratory or field. Hence, biological disciplines usual...
