Geochemical analyses of authigenic carbonates, bivalves, and pore fluids were performed on samples collected from seep fields along the Queen Charlotte Fault, a right lateral transform boundary that separates the Pacific and North American tectonic plates. Samples were collected using grab samplers and piston cores, and were collected during three different research cruises in 2011, 2015, and 2017.

This data publication is a compilation of six different multibeam surveys covering the previously unmapped Queen Charlotte Fault offshore southeast Alaska and Haida Gwaii, Canada. These data were collected between 2005 and 2018 under a cooperative agreement between the U.S. Geological Survey, Natural Resources Canada, and the National Oceanic and Atmospheric Administration. The six source surveys from different multibeam sonars are combined into one terrain model with a 30-m resolution. A complementary polygon shapefile records the extent of each source survey in the output grid.

Black Oystercatcher Morphology and Primary Feather Lengths in Alaska and British Columbia, 2019-2022
These data provide morphological measurements and primary feather length measurements of Black Oystercatcher (Haematopus bachmani) captured at several sites across Alaska and British Columbia between 2019 and 2022. The first table contains mass and morphological measurements of body and bill size. The second table provides lengths of individual primary feathers measured from folded wing photographs using a computer software. These feather lengths are to be used in a size-constrained components analysis to calculate wing shape such as pointedness and convexity.
