Here we quantified mud settling velocity in Barataria Basin, a deltaic estuary in Louisiana (USA), using three independent methods: </span>eddy covariance (one station for 200 days), floc cameras (4 stations at one time), and Rouse profile inversion (14 stations, replicated 10–30 times each). Eddy covariance indicates that settling velocity increases with turbulence, at least within the range experienced at the site (shear rate </span></span><em>G</em><span> up to 10 Hz). Settling velocity increases with salinity (in the 0 to 6 psμ range) for moderate turbulence levels (5 &lt; </span><em>G</em> &lt; 10 Hz), but it is nearly independent of salinity for low levels of turbulence (<em>G</em><span> &lt; 5 Hz). Consistent with this finding, floc camera measurements – taken at low turbulence levels – indicate similar floc sizes for salinities from 0.4 to 20 psu. Settling velocity estimated from a Rouse profile inversion also lacks a dependence on salinity, likely because they were taken at low turbulence levels. This study is novel in that it utilizes three methodologies to independently predict the mud settling velocity, with quantified settling velocity values ranging 0.1–1 mm/s, and with most values between 0.2 and 0.5 mm/s. Overall these measurements confirm that mud is flocculated in both the saline and freshwater zones of Barataria Basin, and that turbulence is the largest factor controlling mud settling velocity. Nonetheless, salinity can increase mud settling velocity up to a factor of two. These results could inform the management of sediment imported into estuaries from freshwater sources, such as through natural drainages, crevasse splays, and engineered river diversions.</span></p></div>","PeriodicalId":50618,"journal":{"name":"Continental Shelf Research","volume":"273 ","pages":"Article 105180"},"PeriodicalIF":2.3,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139538090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the relationship between in-situ farm temperatures and oyster disease and mortality on the southeast coast of Tasmania, Australia using daily observations from three oyster growing areas (Pipe Clay Lagoon, Upper Pittwater, and Lower Pittwater) over three seasons. It is found that a 12-day averaged daily mean temperature is an excellent measure of the occurrence of high mortality. Specifically, a 21-day mean of 23.7 °C resulted in a 70% likelihood of high mortality, which is defined here as oyster losses of &gt;15%. On the other hand, for lower levels of disease and mortality, a 12-day average of daily mean temperature gave the strongest relationship. A 12-day mean of 19.7 °C led to 70% probability of some disease and low mortality.
