UPRM, nd). It is also produced by marine organisms like filterfeeding bivalves in form of feces and pseudofeces. These organisms remove large quantities of suspended matters then transform it into soft sediment (Dankers Zuidema, 1995; Dame 1993). This means that when the density of filter feeder bivalves is high, the amount of excreted matter is also high which may exceed the passive ...
We report here a metagenomic study of the marine planktonic microbiota in which surface (mostly marine) water samples were analyzed as part of the Sorcerer II Global Ocean Sampling expedition. These samples, collected across a severalthousand km transect from the North Atlantic through the Panama Canal and ending in the South Pacific yielded an extensive dataset consisting of million ...
The theoretical knowledge about deepmarine sedimentation acquired during the lecture will be applied in practical exercises. The students will analyse different data sets (seismic data, multibeam bathymetry, sediment cores, welllogs.) and interpret the type of depositional system and its evolution. The course also includes visual description of sediment cores. Kompetenzen: Describe ...
Marine sediment samples and interstitial water from five stations at the southwest of PuertoRico with different characteristics in composition, were submitted to acetylene reduction technique for nitrogen fixation quantifiion and ammonium analysis respectively.

· Marine surface sediment samples were collected at 18 sites in Jobos Bay. Jobos Bay is a semienclosed estuary loed in the south coast of Puerto Rico within the towns of Salinas and Guayama (Fig. 1A). It is the second largest estuary in Puerto Rico. The bay consists of a wide array of natural environments.

Glacialmarine sedimentation rates are low around Antarctica, in part because the climate is so cold and dry that the drybase glaciers carry minimal sediment loads. In addition, the very cold, slowly accumulating and slowly moving permanent ice cover on the Antarctic continent seems to protect the continent from erosion more than it erodes. Glacialmarine sedimentation rates vary widely ...

To establish the current state of marine corridors and the changes that have been made in their physical areas, we used remote sensing images obtained by our liaison from the government in Puerto Rico to qualitatively track factors such as development, sedimentation levels, numbers of marinas, and the physical areas of marine corridors
