Modeling the bottom temperature variation patterns on a coastal marine ecosystem of the Southwestern Atlantic Ocean (El Rincón), with special emphasis on thermal changes affecting fish populations

Bioenergetic Model of the Highly Exploited Shark Mustelus schmitti under a Global Warming Context

“…The parameter values used as input in the model were specified based on research and experimental results (most of them published in [15,26,30,31,33,34,[50][51][52]) or from literaturereported results on closely related species. The individual processes and parameters are described below.…”

“…We use the temperature dependence function found in Thornton and Lessem [57] that has been shown to effectively describe the relationship of temperature with the proportion of C max available to the shark and can graphically be represented as the product of two sigmoid curves (similar to a Q 10 relationship) [8]. The shape of the curve is governed by xk1-4 and te1-4 parameters [12,49], which we estimated from sea bottom temperature models for the El Rincon area [51] and trophic ecology data [30,31,37].…”

“…A daily temperature function, starting on the 1st of January and ending on the 31st of December, was developed using a continuous data series of daily bottom temperature for the El Rincón coastal area between 1980 and 2016, modeled by Elisio et al, [51]. This last study modeled daily temperature for the different depth ranges over the area.…”

“…We ran two scenarios, a baseline using current simulated bottom water temperatures [51] and two high water temperature scenarios. The high-temperature simulations examined the effect of a daily temperature change of +2 and +4 on the predicted growth of individuals, based on "moderate" and "severe" general ocean warming scenarios predicted for the year 2100 according to the IPCC 2022 report [6].…”

Chemically unidentified dissolved organic carbon: A pivotal piece for microbial activity in a productive area of the Northern Patagonian shelf

“…Offshore the 50 m isobath, a frontal system known as Mid-Shelf Front is established during austral spring and summer (Romero et al, 2006;Díaz et al, 2018). This front separates the vertically homogeneous waters of El Rincón (Elisio et al, 2020) from those stratified in the middle shelf (Piola et al, 2018). A particular feature of El Rincón area is the higher salinity in spring and Fig.…”
