Preliminary report on the hydrography and oyster growing conditions in Choctawhatchee Bay, July 11-13, 1961 [PDF]
, 1961 The hydrographic conditions in an estuary such as Choctavhatchee Bay, are complex and dynamic. Temperature and salinity measurements taken at any estuarine sampling station are subject to wide fluctuation depending on local tide and weather conditions ...

Boreas, EarlyView.This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Fisheries Oceanography, EarlyView.ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

PFAS from a Discrete‐Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages
Groundwater, EarlyView.PFAS is conveyed to the coastal intertidal zone from sources across the terrestrial landscape. Discharge of PFAS into the coastal ecosystem is complicated in space and time by the ongoing bi‐directional exchange of terrestrial groundwater and ocean water driven by tidal pumping within discharge areas.

Multi-Scale Marine Object Detection in Side-Scan Sonar Images Based on BES-YOLO
SensorsAiming at the problem of low accuracy of multi-scale seafloor target detection in side-scan sonar images with high noise and complex background texture, a model for multi-scale target detection using the BES-YOLO network is proposed.

Measurements of total alkalinity and inorganic dissolved carbon in the Atlantic Ocean and adjacent Southern Ocean between 2008 and 2010 [PDF]
, 2013 Water column dissolved inorganic carbon and total alkalinity were measured during five hydrographic sections in the Atlantic Ocean and Drake Passage. The work was funded through the Strategic Funding Initiative of the UK's Oceans2025 programme, which ran

Ibis, EarlyView.Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...
