The assessment of anthropogenic impacts and ecological status of coastal waters is an important task to accomplish under the European Water Framework Directive (WFD 2000/60/EEC). Macroalgae are one of the biological quality elements that must be considered, but their assessment has been generally limited to intertidal areas due to the difficulties and costs associated with working in subtidal a...

Beachrocks are generally mapped on the coastline surface and/or in a low depth subtidal zone coastlines and cemented chiefly by carbonate material. Their outcrops may vary from tenth of meters to kilometers length. Along Epirus coast, Greece, beachrocks laying for more than ten kilometers. In present work, we used Unmanned Aerial Vehicles (UAVs), situ sampling, Geographical Information System (...

Seven species of eunicids were found from rocky intertidal and shallow subtidal habitats on the coasts of Taiwan. These polychaetous worms belong to two genera, Eunice Cuvier, 1817 and Nicidion Kinberg, 1865. Among them, five species are new to science, namely Eunice jihueiensis sp. nov., Eunice reticulata sp. nov., Eunice shihmenensis sp. nov., Eunice taoi sp. nov., and Nicidion megabalanicola...

Authigenic aragonite preserves a carbon isotopic record of heterotrophic microbial influences on dissolved inorganic carbon (DIC) in microenvironments within shallow subtidal stromatolites from Highborne Cay, Bahamas. A greater amount of aragonite precipitates when and where respiration, rather than photosynthesis, influences local DIC, which is consistent with sulfate reduction promoting carbo...
