“…Glacial-interglacial sea-level changes may have enhanced fluid flow and promoted dolomitization in both the Bahamas (Swart and Melim, 2000) and the Ordovician strata considered here. While cross-platform variations in submarine groundwater discharge and carbonate saturation state can produce geographically variable δ 44 Ca (Holmden et al, 2012;Shao et al, 2018), our geochemical and geological observations suggest that these factors were negligible in the Great Basin (see the Data Repository).…”

Stratigraphic variability in the geochemistry of sedimentary rocks provides critical data for interpreting paleoenvironmental change throughout Earth history. However, the vast majority of pre-Jurassic geochemical records derive from shallow-water carbonate platforms that may not reflect global ocean chemistry. Here, we used calcium isotope ratios (δ44Ca) in conjunction with minor-element geochemistry (Sr/Ca) and field observations to explore the links among sea-level change, carbonate mineralogy, and marine diagenesis and the expression of a globally documented interval of elevated carbon isotope ratios (δ13C; Hirnantian isotopic carbon excursion [HICE]) associated with glaciation in Upper Ordovician shallow-water carbonate strata from Anticosti Island, Canada, and the Great Basin, Nevada and Utah, USA. The HICE on Anticosti is preserved in limestones with low δ44Ca and high Sr/Ca, consistent with aragonite as a major component of primary mineralogy. Great Basin strata are characterized by lateral gradients in δ44Ca and δ13C that reflect variations in the extent of early marine diagenesis across the platform. In deep-ramp settings, deposition during synglacial sea-level lowstand and subsequent postglacial flooding increased the preservation of an aragonitic signature with elevated δ13C produced in shallow-water environments. In contrast, on the mid- and inner ramp, extensive early marine diagenesis under seawater-buffered conditions muted the magnitude of the shift in δ13C. The processes documented here provide an alternative explanation for variability in a range of geochemical proxies preserved in shallow-water carbonates at other times in Earth history, and challenge the notion that these proxies necessarily record changes in the global ocean.

“…The incorporation of geomarkers such as Sr isotopes ( 87 Sr/ 86 Sr) could help to discriminate between the use of different environments, especially in freshwater and coastal environments (Walther & Nims, 2015; Shao et al, 2018). In addition, field or experimental studies are necessary to characterize the relationship between other ratios such as Ba/Ca with salinity.…”

“…Therefore, the methodology applied in this study does not clearly detect movement between environments with salinities higher than that measured in the open ocean. The incorporation of geomarkers such as strontium isotopes ( 87 Sr/ 86 Sr) or stable isotopes could contribute to discriminating the use of different environments, especially in coastal and continental environments (Walther & Nims, 2015; Shao et al, 2018).…”

The white mullet, Mugil curema, is a widely distributed euryhaline species, the migratory behaviour of which is poorly understood. The objective of this work was to study the large‐scale habitat use of this species for the first time. Several environments were considered, such as euryhaline and hypersaline lagoons, the sea, and a river, distributed in the Central Pacific (Mexico) and Atlantic (Gulf of Mexico, Caribbean Sea‐Venezuela, and north‐eastern Brazil). Otolith core‐to‐edge Sr/Ca ratios of 163 fish, determined by laser ablation inductively coupled plasma mass spectrometry, were used to study the salinity‐habitat migration history of the fish. Fish from Mexico (Tamiahua Lagoon, n = 4; Alvarado Lagoon, n = 2), Venezuela (n = 1), and Brazil (n = 12) (11.1% of the total) showed high Sr/Ca values at early life stages and were classified as marine estuarine opportunists. Two specimens (from Alvarado Lagoon and Balsas River, Mexico) showed Sr/Ca values consistently below the high salinity guide value (salinity < 33.5). For the rest of the fish (87.1%), the Sr/Ca ratio suggested a displacement from the estuary towards the sea or hypersaline environments, and so these fish were classified as estuarine migrants. A change‐point analysis identified six individuals with a single stable otolith Sr/Ca signature through ontogeny (three from Brazil, one from Venezuela, and two from Tamiahua Lagoon, Mexico), suggesting limited displacement between environments with different salinities. The rest of the individuals showed between two and 10 changes in stable Sr/Ca signatures (mean = 4.07 ± 1.85). The highest number of changes in Sr/Ca ratio (4.87 ± 1.1) was found in fish from Laguna Madre (Mexico) and the lowest was found in fish from Brazil (3.27 ± 1.70) (H = 19.8, p = 0.002). Otolith Sr/Ca time series suggest that the migratory estuarine pattern is the most common throughout the study area. This work highlights that the sustainable use of M. curema depends on the conservation of estuaries and the corridors between them and other environments such as lagoons, rivers, mangroves and the sea.

“…However, the lower concentrations of Sr 2+ observed in the European hake [28] differed from those observed in black porgy in this study, potentially due to the freshwater that was added, which was groundwater containing higher concentrations of Sr 2+ . Recent studies have shown that the ratio of trace element concentration of otolith could reflect the change of elements, salinity or water temperature [41] as a tool to know about the fish migration between freshwater and sea water [42] [43], which is also a future application of this study.…”

Due to the decreasing resources of both inshore and offshore fisheries, many organizations have released fry to enhance their stock in recent years. The discrimination between wild and hatchery-reared individuals must be performed to assess the efficiency of the release. Fresh groundwater is generally used by hatchers in southwestern Taiwan to decrease salinity and to promote the growth of larvae prior to feeding; thus, the elemental composition of the otolith may be different in stocks, and this difference may be used for identification. This study used Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS) to analyze the trace elements in the nuclei of otoliths from black porgy Acanthopagrus schlegelii, including six hatchery reared specimens from the Tainan County, three recaptured marked and ten captured unmarked specimens from the Miaoli County in Northwestern coast of Taiwan. Among the six hatchery and three recaptured marked specimens, which ranged from 4.9 to 23.4 cm in body length, the nucleus zone (relative to within 5 cm in size growth) of the otoliths showed higher magnesium concentrations than that observed on both edges. The distribution was similar to an inverse "V" shape. The otoliths also showed lower manganese concentrations near the nucleus and had higher values near the edges, resulting in a distribution similar to a "U" shape. According to the appeared shape of Mg 2+ /Ca 2+ and Mn 2+ /Ca 2+ ratio in the central area of the nucleus zone, this study determined six specimens which were from hatchery reared and three specimens were from wild among ten unmarked specimens captured from
