A low-power (<10 mW), physically small (15.6 cm long × 3.2 cm diameter), lightweight (600 g Cu; alternatively, 200 g Al), robust, and simply calibrated pitot-static tube to measure mean speed and turbulence dissipation (ε ) is described and...

Physical exchange between estuarine and continental shelf waters impacts flushing dynamics of the
estuary and determines rates of ocean inputs of nutrients and plankton. To investigate the occurrence
and propagation of shelf water intrusions into...

With the ongoing crisis of biodiversity loss and limited resources for conservation, the concept of biodiversity hotspots has been useful in determining conservation priority areas. However, there has been limited research into how temporal...

Climate impact studies often require the selection of a small number of climate scenarios. Ideally, a subset would have simulations that both (1) appropriately represent the range of possible futures for the variable/s most important to the impact...

The volcanic (~45-10 Ma) and plutonic rocks (~37-12 Ma) comprising the Western Cascades extend from northernmost California to southern British Columbia and are ancestral to modern arc magmatism. The ancestral arc hosts a series of small plutons...

Understanding sandbar dynamics and variability is integral to developing a predictive capacity for nearshore flows, sediment transport, morphological change, and ultimately for determining coastline exposure to damaging storm waves. Here we report...

The spin-statistics connection has been proved for nonrelativistic quantum mechanics (Jabs in Found Phys 40:776–792, 2010). The proof is extended here to the relativistic regime using the parametrized Dirac equation. A causality condition is not...

To understand causes and consequences of landscape change, it is often not enough to simply detect change. Rather, the agent causing the change must also be determined. Here, we describe and test a method of change agent attribution built on four...

Museums, aquariums, and technology centers are informal learning environments that facilitate the understanding of scientific phenomena while supporting self-motivated learning. Families are a social group that frequently visits these sites. There...

Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This...

We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. These loops illustrate the temporal...

Network theory is applied to an array of streamflow
gauges located in the Coast Mountains of British
Columbia (BC) and Yukon, Canada. The goal of the analysis
is to assess whether insights from this branch of mathematical
graph theory can be...

Many trace elements (e.g., Zn, Cd, Mo) are essential phytoplankton micronutrients, making them crucial to the marine ecosystem and ultimately the carbon cycle. Because of this association trace metals are also utilized in paleoceanographic studies...

Many nations that invest in aquaculture and fisheries for improved nutrition and food security are located in areas prone to natural disasters, such as typhoons. While all residents are vulnerable to the effects of disasters, research suggests...

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...

The Southeast Pacific, which encompasses the coasts of Peru and Chile, is one of the world's most productive regions resulting principally from the upwelling of subsurface nutrient-rich waters. Over the satellite altimetry era, there have been...

A three-dimensional sea ice model is presented with resolved snow thickness variations and
melt ponds. The model calculates heating from solar radiative transfer and simulates the formation and
movement of brine/melt water through the ice system....

In the mid-2000s the U.S. west coast oyster industry experienced several years of significant production failures. This industry has been referred to as the “canary in a coal mine” for ocean acidification (OA). Industry-led collaboration with...

We estimate fluid sources around a subducted seamount along the northern Hikurangi subduction
margin of New Zealand, using thermomechanical numerical modelling informed by
wedge structure and porosities from multichannel seismic data. Calculated...

During the last 3 decades, tagging technology has been used to study different
aspects of cetacean ecology. Tags implanted in animal’s blubber, muscle and surrounding tissue
have produced successful results, providing information on long-term...
