Abstract: Studies on gender disparity in academia generate constructive discussions to promote equality. In a recently published study, AlShebli et al. 2020 analyzed the role of informal mentorship in supporting early-career scientists and how gender may shape scientific careers. Besides presenting methodological flaws, the study culminates in the authors' conclusion that mentoring quality is determined by the mentor's gender, suggesting that female protégés reap more benefits when mentored by males rather than equally-impactful females. Despite acknowledging that possible causal factors were not considered in their analyses, they attest that the success of female scientists' careers relies on opposite-gender mentorships in terms of publication and impact. Although the authors state that these findings add a new perspective to the policy debate on the best ways to elevate the women in science, their conclusions reinforce the traditional patriarchal, biased scientific structure that stimulates a poorly ersified hierarchical chain in STEM. Here we highlight the study's methodological weaknesses and major issues that must be addressed to avoid the perpetuation of gender disparity in science.

Abstract: Abstract. The response of the hydrological cycle to anthropogenic climate change, especially across the tropical oceans, remains poorly understood due to the scarcity of long instrumental temperature and hydrological records. Massive shallow-water corals are ideally suited to reconstructing past oceanic variability as they are widely distributed across the tropics, rapidly deposit calcium carbonate skeletons that continuously record ambient environmental conditions, and can be s led at monthly to annual resolution. Climate reconstructions based on corals primarily use the stable oxygen isotope composition (δ18O), which acts as a proxy for sea surface temperature (SST), and the oxygen isotope composition of seawater (δ18Osw), a measure of hydrological variability. Increasingly, coral δ18O time series are paired with time series of strontium-to-calcium ratios (Sr/Ca), a proxy for SST, from the same coral to quantify temperature and δ18Osw variability through time. To increase the utility of such reconstructions, we present the CoralHydro2k database, a compilation of published, peer-reviewed coral Sr/Ca and δ18O records from the Common Era (CE). The database contains 54 paired Sr/Ca–δ18O records and 125 unpaired Sr/Ca or δ18O records, with 88 % of these records providing data coverage from 1800 CE to the present. A quality-controlled set of metadata with standardized vocabulary and units accompanies each record, informing the use of the database. The CoralHydro2k database tracks large-scale temperature and hydrological variability. As such, it is well-suited for investigations of past climate variability, comparisons with climate model simulations including isotope-enabled models, and application in paleodata-assimilation projects. The CoralHydro2k database is available in Linked Paleo Data (LiPD) format with serializations in MATLAB, R, and Python and can be downloaded from the NOAA National Center for Environmental Information's Paleoclimate Data Archive at 0.25921/yp94-v135 (Walter et al., 2022).

Massive shallow-water corals are ideally suited to reconstructing past oceanic variability as they are widely distributed across the tropics, rapidly deposit calcium carbonate skeletons that continuously record ambient environmental conditions, and can be s led at monthly to annual resolution. Most coral-based reconstructions utilize stable oxygen isotope composition (δ18O) that tracks the combined change in sea surface temperature (SST) and the oxygen isotopic composition of seawater (δ18Osw), a measure of hydrologic variability. Increasingly, coral δ18O time series are paired with time series of strontium-to-calcium ratios (Sr / Ca), a proxy for SST, from the same coral to quantify temperature and δ18Osw variability through time.
