In the future, Earth will be warmer, precipitation events will be more extreme, global mean sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes will also occur at an accelerated rate as developed areas increase in size and population density. We now...

The 8.2 ka event was the last deglacial abrupt climate event. A reduction in the Atlantic meridional overturning circulation (AMOC) attributed to the drainage of glacial Lake Agassiz may have caused the event, but the freshwater signature of Lake Agassiz discharge has yet to be identified in δ¹⁸O of foraminiferal...

Managing for species using current weather patterns fails to incorporate the uncertainty associated with future climatic conditions; without incorporating potential changes in climate into conservation strategies, management and conservation efforts may fall short or waste valuable resources. Understanding the effects of climate change on species in the Great Plains of...
Mg batteries have potential advantages in terms of safety, cost, and reliability
over existing battery technologies, but their practical implementations are hindered
by the lack of amenable high-voltage cathode materials. The development
of cathode materials is complicated by limited understandings of the unique
divalent Mg²⁺ ion electrochemistry and the interaction/transportation...
Temperature anomalies can identify locations of seeps of groundwater into surface waters.
However, the method’s sensitivity to details such as thermometer burial depth, sediment material, seep
velocity, and surface water current are largely unknown. We report on a series of laboratory flume experiments
in which controlled seeps under variable sediment...

Due to lower sea levels during the Last Glacial Maximum (LGM), tidal energy dissipation was shifted from the shallow margins into the deep ocean. Here using a high-resolution tide model, we estimate that global energy fluxes below 200 m depth were almost quadrupled during the LGM. Applying the energy fluxes to...

We show how a distributed borehole flowmeter can be created from armored Fiber Optic
cables with the Active-Distributed Temperature Sensing (A-DTS) method. The principle is that in a flowing
fluid, the difference in temperature between a heated and unheated cable is a function of the fluid velocity.
We outline the...

Understanding controls on the stable isotopic composition of precipitation and vapor in the West Pacific Warm Pool is vital for accurate representation of convective processes in models and correct interpretation of isotope-based paleoclimate proxies, yet a lack of direct observational evidence precludes the utility of these isotopic tracers. Results from...

Deuterium to hydrogen (D/H) ratios in Earth’s hydrologic cycle have long served as important
tracers of climate processes, yet the global HDO budget remains poorly constrained because of uncertainties
in the isotopic compositions of continental evapotranspiration and runoff. Here bias-corrected satellite retrievals of
HDO and H₂O concentrations from the Tropospheric...

A three-dimensional, process-based model of the ocean’s carbon and nitrogen cycles, including
13C and 15N isotopes, is used to explore effects of idealized changes in the soft-tissue biological pump. Results
are presented from one preindustrial control run (piCtrl) and six simulations of the Last Glacial Maximum
(LGM) with increasing values...
