Unconventional Sea Surface Temperature Regime Around Japan in the 2000s–2010s: Potential Influences on Major Fisheries Resources

Frontiers in Marine Science, 2020
Climate-change associated changes in oceanographic conditions, particularly sea surface temperatures (SSTs), have systematically affected many marine fisheries resources around Japan.

Accumulation reconstruction and water isotope analysis for 1736–1997 of an ice core from the Ushkovsky volcano, Kamchatka, and their relationships to North Pacific climate records [PDF]

Climate of the Past, 2014
An ice core was retrieved in June 1998 from the Gorshkov crater glacier at the top of the Ushkovsky volcano, in central Kamchatka. This ice core is one of only two recovered from Kamchatka so far, thus filling a gap in the regional instrumental climate ...

Understanding the impact of environmental variability and fisheries on the red sea urchin population in Baja California

Frontiers in Marine Science, 2022
IntroductionThe red sea urchin fishery is one of the most important fisheries in Baja California and the only urchin fishery in México; yet little is known on understanding how local, regional, and oceanic environmental variability may affect red sea ...

Potential factors affecting survival differ by run-timing and location: linear mixed-effects models of Pacific salmonids (Oncorhynchus spp.) in the Klamath River, California. [PDF]

PLoS ONE, 2014
Understanding factors influencing survival of Pacific salmonids (Oncorhynchus spp.) is essential to species conservation, because drivers of mortality can vary over multiple spatial and temporal scales.

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

Meta-Analysis of Salmon Trophic Ecology Reveals Spatial and Interspecies Dynamics Across the North Pacific Ocean

Frontiers in Marine Science, 2021
We examined spatial patterns in diet, trophic niche width and niche overlap for chum, pink and sockeye salmon across the North Pacific during 1959–1969. This is a baseline period before major hatchery enhancement occurred coinciding with a negative phase

Asymmetry in the effect of North Atlantic sea surface temperature on the eddy‐driven jet

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Projections of climate over Europe and the Atlantic are uncertain due to the uncertainty surrounding future changes in North Atlantic sea surface temperatures (SSTs). Here, we demonstrate that warming in the North Atlantic Ocean is linked to a transition to a negative phase of the North Atlantic Oscillation, as well as to an equatorward displacement of

Increased amplitude of the North Pacific Gyre Oscillation (NPGO) towards recent: evidence from tree-ring based reconstruction since 1596

, 2021
This dataset provides a reconstruction of the NPGO from 1596 onwards from nineteen NPGO sensitive tree-ring chronologies in Himalayan Mountains, Rocky Mountains, Coastal Mountains and Alaskan Mountain Range.

California coastal upwelling onset variability: cross-shore and bottom-up propagation in the planktonic ecosystem. [PDF]

PLoS ONE, 2013
The variability of the California Current System (CCS) is primarily driven by variability in regional wind forcing. In particular, the timing of the spring transition, i.e., the onset of upwelling-favorable winds, varies considerably in the CCS with ...

State of the California Current Ecosystem in 2021: Winter is coming?

Frontiers in Marine Science, 2022
In late 2020, models predicted that a strong La Niña would take place for the first time since 2013, and we assessed whether physical and biological indicators in 2021 were similar to past La Niñas in the California Current Ecosystem (CCE).
