Mean coral cover has reportedly declined by over 15% during the last 30 years across the central Great Barrier Reef (GBR). Here, we present new data that documents widespread reef development within the more poorly studied turbid nearshore areas (<10 m depth), and show that coral cover on these reefs averages 38% (twice that reported on mid- and outer-shelf reefs). Of the surveyed seafloor area...

[1] Drifting cylindrical traps and the flux proxy Th indicate more than an order of magnitude higher sinking fluxes of particulate carbon and 234Th in January 2009 than measured by a time‐series conical trap used regularly on the shelf of the west Antarctic Peninsula (WAP). The higher fluxes measured in this study have several implications for our understanding of the WAP ecosystem. Larger sink...

This work presents an investigation of ice shelf vibration using a model based on shallow water approximation. The study focused the effect changes in draft and both time-domain frequency-domain results. used radiation condition for energy propagation into shelf. Furthermore, balance relation was derived to investigate flow within system. Results show that can significantly impact shelf’s syste...

Wave climate over the North Indian Ocean region experienced a paradigm shift in recent past, indicating an increase extremes. Wind-waves and swell climatology have shown increasing trend this region, having direct implications on coastal zone dynamics surrounding mainland island features. The present study aims to investigate wave–current-surge interaction characteristics shallow continental sh...

Shallow, near-shore water habitats on the continental shelf of the Northeast Atlantic have been productive fishing areas in the past. Here, we review the present knowledge about (i) recent trends in the abundance of plaice and cod in these habitats and (ii) hypotheses regarding the factors responsible for any trends. At present, only a few studies exist on the trends of abundance of plaice or c...

Methane is the second most important greenhouse gas contributing to climate warming. The open ocean is a minor source of methane to the atmosphere. We report intense methane emissions from the near-shore southern region of the North Sea characterized by the presence of extensive areas with gassy sediments. The average flux intensities (~130 μmol m(-2) d(-1)) are one order of magnitude higher th...

A multi-spectral classification and quantification technique is developed for estimating chlorophyll a concentrations, Chl, in shallow oceanic waters where light reflected by the bottom can contribute significantly to the above-water remote-sensing reflectance spectra, Rrs(k). Classification criteria for determining bottom reflectance contributions for shipboard Rrs(k) data from the west Florid...
