Integrating Multiple Data Sources Improves Abundance Estimation in Spatial Capture-Recapture Models. [PDF]

open access: yesEcol Evol
This study demonstrates how integrating multiple data streams improves abundance estimation for a wide‐ranging marine population, eastern North Pacific blue whales. The application of this approach is valuable to accurately track population size which is critical to guide conservation and management strategies.

Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

open access: yesGeophysical Research Letters
Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments.

Low Resighting Rate of Entangled Humpback Whales Within the California, Oregon, and Washington Region Based on Photo-Identification and Long-Term Life History Data

open access: yesFrontiers in Marine Science, 2022
Bycatch, commonly referred to as entanglement, is a leading source of human-caused mortality of baleen whales. A better understanding of the individuals that survive (or perish from) their entanglement can help reduce the risk of bycatch by informing ...

Complex Structure in the Nootka Fault Zone Revealed by Double‐Difference Tomography and a New Earthquake Catalog

open access: yesGeochemistry, Geophysics, Geosystems, 2022
We employ an automatic earthquake detection algorithm to seismic waveforms recorded between the years 2000 and 2020 in southwest British Columbia. 32,121 events which possess at least three paired P‐ and S‐wave arrival times are located, compared to 21 ...

Mid-Miocene to Present Upper-Plate Deformation of the Southern Cascadia Forearc: Effects of the Superposition of Subduction and Transform Tectonics

open access: yesFrontiers in Earth Science, 2022
The southern Cascadia forearc undergoes a three-stage tectonic evolution, each stage involving different combinations of tectonic drivers, that produce differences in the upper-plate deformation style.

A new chronology for tsunami deposits prior to the 1700 CE Cascadia earthquake from Vancouver Island, Canada

open access: yesScientific Reports, 2022
Coastal deposits at Tofino, Ucluelet, and Port Alberni in Vancouver Island along the Cascadia subduction zone were re-examined to improve the earthquake history of the southwest coast of Canada.

Blue Whale Body Condition Assessed Over a 14-Year Period in the NE Pacific: Annual Variation and Connection to Measures of Ocean Productivity

open access: yesFrontiers in Marine Science, 2022
Large marine mammals can serve as an indicator of the overall state of the environment due to their apex position in marine food webs and their functions as sentinels of change.

Impact‐Induced Seafloor Deformation From Submarine Landslides: Diagnostic of Slide Velocity?

open access: yesGeophysical Research Letters, 2023
Submarine landslides shape continental margins, transfer massive amounts of sediment downslope, and can generate deadly and destructive tsunamis. Submarine landslides are common globally, yet constraining hazard potential of future events is limited by a

The Cascadia Initiative: A Sea Change In Seismological Studies of Subduction Zones [PDF]

open access: yesOceanography, 2014
Increasing public awareness that the Cascadia subduction zone in the Pacific Northwest is capable of great earthquakes (magnitude 9 and greater) motivates the Cascadia Initiative, an ambitious onshore/offshore seismic and geodetic experiment that takes ...
