“…Several studies have focused their efforts on the development of calibrations for deep water genera, such as Krithe, which are found in the Pacific, Atlantic and Arctic oceans (Corrège and De Deckker, 1997;Cronin et al, 1996;Dwyer et al, 1995Dwyer et al, , 2002Elmore et al, 2012;Farmer et al, 2011Farmer et al, , 2012Rodriguez et al, 2020). Other studies have investigated species found in shallow marine environments, such as those from the genus Loxoconcha (Cronin et al, 2003(Cronin et al, , 2005a and Cyprideis (Holmes and De Deckker, 2016;Roberts et al, 2020). However, there is uncertainty in temperature calibrations to Mg/Ca of marine ostracods due to the low number of calibrations developed in comparison to the number of known species (Holmes and De Deckker, 2012) and the contrasting cali-bration slopes observed in different species (Yamada et al, 2014).…”
