Rapid changes in ocean circulation and climate have been observed in marine-sediment and ice cores over the last glacial period and deglaciation, highlighting the non-linear character of the climate system and underlining the possibility of rapid climate shifts in response to anthropogenic greenhouse gas forcing. To date, these rapid changes in climate and ocean circulation are still not fully explained. One obstacle hindering progress in our understanding of the interactions between past ocean circulation and...

High-resolution surface global solar radiation and the diffuse component dataset over China

Hou Jiang & Ning Lu
Surface solar radiation drives the water cycle and energy exchange on the earth's surface, and its diffuse component can promote carbon uptake in ecosystems by increasing the plant productivity. The accurate knowledge of their spatial distribution is of great importance to many studies and applications, such as the estimation of agricultural yield, carbon dynamics of terrestrial systems, site selection of solar power plants, as well as trends of regional climate changes. Therefore, we produce the...

Abundance and morphometry of Daphnia lumholtzi in Lake Texoma, OK, USA in 2010-2011, supplement to: Beyer, Jessica E; Hambright, K David (2019): The niche and morphology of the invasive Daphnia lumholtzi in a subtropical reservoir, 20 years after invasion.

Bioturbators such as sediment-dwelling marine bivalves are ecosystem engineers that enhance sediment-water exchange and benthic-pelagic coupling. In shallow coastal areas, bivalves are exposed to frequent disturbance and salinity stress that might negatively affect their activity and physiological performance; however, the mechanisms underlying these effects are not fully understood. We investigated the effects of osmotic stress (low and fluctuating salinity) and repeated burrowing on aerobic and contractile capacity of the foot muscle (assessed by the activity...

Records of Neogene ocean carbonate chemistry using the boron isotope pH proxy, supplement to: Sosdian, Sindia M; Greenop, Rosanna; Hain, Mathis P; Foster, Gavin L; Pearson, Paul N; Lear, Caroline H (2018): Constraining the evolution of Neogene ocean carbonate chemistry using the boron isotope pH proxy. Earth and Planetary Science Letters, 498, 362-376

Sindia M Sosdian, Rosanna Greenop, Mathis P Hain, Gavin L Foster, Paul N Pearson & Caroline H Lear
Over the course of the Neogene, the Earth underwent profound climatic shifts from the sustained warmth of the middle Miocene to the development of Plio-Pleistocene glacial-interglacial cycles. Major perturbations in the global carbon cycle have occurred alongside these shifts, however the lack of long- term carbonate system reconstructions currently limits our understanding of the link between changes in CO2, carbon cycling, and climate over this time interval. Here we reconstruct continuous surface ocean pH, CO2,...

Most of the world's permafrost is located in the Arctic, where its frozen organic carbon con-tent makes it a potentially important influence on the global climate system. The Arctic climate appears to be changing more rapidly than the lower latitudes, but observational data density in the region is low. Permafrost thaw and carbon release into the atmosphere is a positive feed-back mechanism that has the potential for climate warming. It is therefore particularly im-portant to...
