Shelf-edge deltas and drowned barrier–island complexes on the northwest Florida outer continental shelf
A high-resolution multibeam survey of the northwest Florida shelf mapped six relict shelf-edge deltas, each with a drowned barrier–island system developed on its south and southwestern rims. The deltas appear to have formed during periods of sealevel stasis that occurred between 58,000 and 28,000 years ago. The barrier islands formed on the deltas during periods of slow regression during this s...
متن کاملPersistent transport barrier on the West Florida Shelf.
Analysis of drifter trajectories in the Gulf of Mexico has revealed the existence of a region on the southern portion of the West Florida Shelf (WFS) that is not visited by drifters that are released outside of the region. This so-called "forbidden zone" (FZ) suggests the existence of a persistent cross-shelf transport barrier on the southern portion of the WFS. In this letter a year-long recor...
متن کاملNo barrier to emergence of bathyal king crabs on the Antarctic shelf.
Cold-water conditions have excluded durophagous (skeleton-breaking) predators from the Antarctic seafloor for millions of years. Rapidly warming seas off the western Antarctic Peninsula could now facilitate their return to the continental shelf, with profound consequences for the endemic fauna. Among the likely first arrivals are king crabs (Lithodidae), which were discovered recently on the ad...
متن کاملEthylene vinyl alcohol: a review of barrier properties for packaging shelf stable foods.
Ethylene vinyl alcohol (EVOH) is one of the best known flexible thermoplastic oxygen barrier materials in use today. It is especially important for refrigerated and shelf-stable foods where oxygen deteriorates the quality of packaged products and reduces their shelf life. EVOH accounts for a majority of thermoplastic barrier materials used for rigid or semi-rigid retortable food containers. How...
متن کاملCyclone pumping, sediment partitioning and the development of the Great Barrier Reef shelf system: a review
The modern Great Barrier Reef (GBR) is part of the world’s largest and best known mixed terrigenous-carbonate continental margin. The GBR shelf contains three shore-parallel sedimentary belts: an inner shelf zone of terrigenous sedimentation at depths of 0–22m; a middle shelf zone of sediment starvation at depths of 22–40m; and an outer shelf reef tract with its inner edge at ca. 40m depth. The...
