Data from: The latest freshwater giants: a new Peltocephalus (Pleurodira: Podocnemididae) turtle from the Late Pleistocene of the Brazilian Amazon
<p>Overkill of large mammals is recognised as a key driver of Pleistocene megafaunal extinctions in the Americas and Australia. While this phenomenon primarily affected mega-mammals, its impact on large Quaternary reptiles has been debated. Freshwater turtles, due to the scarcity of giant forms in the Quaternary record, have been largely neglected in such discussions. Here we present a new giant podocnemidid turtle, <em>Peltocephalus maturin</em> sp. nov., from the Late Pleistocene Rio Madeira Formation in the Brazilian Amazon, that challenges this assumption. Morphological and phylogenetic analyses of the holotype, a massive partial lower jaw, reveal close affinities to extant Amazonian species and suggests an omnivorous diet. Body size regressions indicate <em>Pe. maturin</em> possibly reached about 180 cm in carapace length and is amongst the largest freshwater turtles ever found. This finding presents the latest known occurrence of giant freshwater turtles, hinting at coexistence with early human inhabitants in the Amazon.</p>

Data from: The largest freshwater odontocete: a South Asian river dolphin relative from the Proto-Amazonia
<p>Several dolphin lineages have independently invaded freshwater systems. Among these, the evolution of the South Asian river dolphin <em>Platanista </em>and its closest relatives (Platanistidae) remains virtually unknown as fossils are scarce. Here, we describe <em>Pebanista</em> <em>yacuruna</em> gen. et sp. nov., a fossil dolphin from the Miocene proto-Amazonia of Peru, recovered in phylogenies as the closest relative of <em>Platanista</em>. Morphological characters such as an elongated rostrum and large supraorbital crests, along with ecological interpretations, indicate that this new taxon was fully adapted to freshwater environments. <em>Pebanista</em> constitutes the largest freshwater odontocete known, with an estimated body length of 3 meters. It highlights the ample resource availability in the region, supporting biotic diversity during the Early to Middle Miocene. The finding of <em>Pebanista</em> in proto-Amazonian layers attests that platanistids ventured into freshwater ecosystems not only in South Asia, but also in South America, long before and independently of modern Amazon River dolphin <em>Inia</em>, during a crucial moment for the evolution of the Amazonian realm.</p>
Data for: Subglacial freshwater driven speedup of East Antarctic outlet glacier retreat
<p>Recent studies have revealed the presence of a complex freshwater system underlying the Aurora Subglacial Basin (ASB), a region of East Antarctica that contains ~7 m of global sea level potential in ice mainly grounded below sea level. Yet, the impact that subglacial freshwater has on driving the evolution of the dynamic outlet glaciers that drain this basin has yet to be tested in a coupled ice sheet-subglacial hydrology numerical modeling framework. Here, we project the evolution of the primary outlet glaciers draining the ASB (Moscow University Ice Shelf, Totten, Vanderford, and Adams Glaciers) in response to an evolving subglacial hydrology system and to ocean forcing through 2100, following low and high CMIP6 emission scenarios. By 2100, ice-hydrology feedbacks enhance the ASB's 2100 sea level contribution by ~30% (7.50 mm to 9.80 mm) in high emission scenarios and accelerate retreat of Totten Glacier's main ice stream by 25 years. Ice-hydrology feedbacks are particularly influential in the retreat of the Vanderford and Adams Glaciers, driving an additional 10 km of retreat in fully-coupled simulations relative to uncoupled simulations. Hydrology-driven ice shelf melt enhancements are the primary cause of domain-wide mass loss in low emission scenarios, but are secondary to ice sheet frictional feedbacks under high emission scenarios. The results presented here demonstrate that ice-subglacial hydrology interactions can significantly accelerate retreat of dynamic Antarctic glaciers and that future Antarctic sea level assessments that do not take these interactions into account might be severely underestimating Antarctic Ice Sheet mass loss. </p> <p>In this data publication, we present the model output and results associated with the following manuscript recently submitted to the Journal of <em>Geophysical Research: Earth Surface</em>: "Subglacial discharge accelerates ocean driven retreat of Aurora Subglacial Basin outlet glaciers over the 21st century". We include yearly ice sheet model output between 2017-2100 for eight numerical ice-subglacial hydrology model runs. We also include the ice sheet and subglacial hydrology model initial states. In addition, we include all ocean forcing time-series (temperature and salinity for the low emission and high emission climate forcing scenarios for three glacial regions), which are used as input into the melt parameterization. Lastly, we include a MATLAB script that contains the code used to couple the ice-subglacial hydrology models as well as a "readme" file with further information on all data in this publication.</p>
Dissolved calcium and pH raster layers for freshwater environments in Canada and the USA
<p>Calcium concentration and pH are key parameters that are linked to multiple chemical and biological processes in freshwater environments. This dataset presents high-resolution (10 x 10 km) interpolated raster layers for these two variables across Canada and the continental USA. These layers were generated via spatial interpolation (Kriging with a fixed zero nugget) after comparison of multiple interpolation methods, using water quality data for lakes and rivers compiled from multiple sources. This is the first time that such data have been made available at this scale and resolution, providing a valuable resource for research, including projects evaluating risks from environmental change, pollution, and invasive species. </p>
