In Katmai National Park, Alaska, USA, we have seen changes in the number of brown bears and sea otters. The animals a species habitat can support is called carrying capacity. Even though live on land otters ocean, these two mammals share coastal habitats. Bears eat salmon, other fish, plants, clams, beached whales. Sea feed clams marine invertebrates. All foods are influenced by ocean. Recently...

We summarize results of two independent studies on plastic pollution in the marine environment that overlap in time and space. One study evaluated the abundance of anthropogenic debris on 37 sandy beaches bordering the Salish Sea in Washington State while the other characterized plastic debris in surface waters of the Salish Sea and the Inside Passage to Skagway, Alaska. Both studies concluded ...

Laysan albatross (Phoebastria immutabilis) ingest plastic marine debris of a wide range of shape, sizes and sources. To better characterize this plastic and provide insights regarding its provenance and persistence in the environment, we developed a simple method to classify plastic fragments of unknown origin according to the resin codes used by the Society of Plastics Industry. Known plastics...

This paper reexamines policies and outcomes concerning the NY Bight Restoration Plan, and the NY-NJ Harbor Estuary Program (NYNJHEP) precipitated by washups of marine debris and medical wastes in the New York Bight some 25-years ago. Findings indicate progress has been made but further work is necessary. Extensive beach closures have not occurred since 1987-88, although localized closings occur...

Ingestion of artificial debris is considered as a significant stress for wildlife including sea turtles. To investigate how turtles react to artificial debris under natural conditions, we deployed animal-borne video cameras on loggerhead and green turtles in addition to feces and gut contents analyses from 2007 to 2015. Frequency of occurrences of artificial debris in feces and gut contents col...

The Internet of Underwater Things (IoUT) is an emerging communication ecosystem developed for connecting underwater objects in maritime and environments. IoUT technology intricately linked with intelligent boats ships, smart shores oceans, automatic marine transportations, positioning navigation, exploration, disaster prediction prevention, as well monitoring security. has influence at various ...

the asmari formation at nil anticline area has been studied in order to determine faunal assemblages, the age and the paleoecology. paleontological and biostratigraphical studies led to the identification of 5 faunal assemblages. as a result, the age of the asmari formation in this section, with 291m thickness, is rupelian/chattian-burdigalian. extension of the large benthic foraminifera sugges...
