Decadal change in deep-ocean dissolved oxygen in the North Atlantic Ocean and North Pacific Ocean Open
Declining dissolved oxygen concentrations are documented at upper and mid ocean depths, but less is known about the deep ocean. Long time-series measurements of dissolved oxygen analyzed with Winkler titration over several decades reveal r…

Spatial and Temporal Interplay Between Oceanic Circulation and Biological Production in Shaping Carbon Export Off the California Coast Open
A major challenge in understanding the oceanic carbon cycle is estimating the sinking flux of organic carbon exiting the sunlit surface ocean, termed carbon export. Existing algorithms derive carbon export from satellite ocean color, but n…

Coastal upwelling drives ecosystem temporal variability from the surface to the abyssal seafloor Open
Long-term biological time series that monitor ecosystems across the ocean’s full water column are extremely rare. As a result, classic paradigms are yet to be tested. One such paradigm is that variations in coastal upwelling drive changes …

Decadal Time‐Series Depletion of Dissolved Oxygen at Abyssal Depths in the Northeast Pacific Open
Dissolved oxygen depletion in the global ocean is well documented over several decades from the surface ocean to abyssal depths. This decline is especially prevalent in the Northeast Pacific. A significant decline in dissolved oxygen has b…

Abyssal epibenthic holothurians respond differently to food quantity and concentration fluctuations over a decade of daily observation (2007–2017) Open
Deep-sea holothurians rely on food settling from overlying waters onto the seafloor. Long-term, high-temporal-resolution sampling is required to understand how changes in different aspects of food supply elicit different responses across s…

Chemotactile social recognition in the blue-ringed octopus, Hapalochlaena maculosa Open
Social recognition is the ability of individuals in a species to differentiate among conspecifics based on their identity or biologically meaningful demographic. Despite evidence that they have sophisticated brains, complex behavioural rep…

Deep-Sea Echinoid Trails and Seafloor Nutrient Distribution: Present and Past Implications Open
The movement patterns of deep-sea bioturbational fauna are believed to be the result of the organism’s interactive response to the perceived spatial distribution of nutritional resources on the seafloor. To address this hypothesis, we exam…

Changes in phytoplankton and biomineral content of particles during episodic fluxes to abyssal depth Open
Large episodic pulses of particulate organic carbon (POC) at the deep‐sea (~ 4000 m) time‐series Sta. M in the Northeast Pacific Ocean have increased in frequency and magnitude over the past 32 years. We inferred the ecological drivers of …

Faculty Opinions recommendation of Fires prime terrestrial organic carbon for riverine export to the global oceans. Open
Black carbon (BC) is a recalcitrant form of organic carbon (OC) produced by landscape fires. BC is an important component of the global carbon cycle because, compared to unburned biogenic OC, it is selectively conserved in terrestrial and …
