@mhaltuch can you list some surveys here that come to mind when you think about DFO and Alaska data that could help inform US West Coast species? I am guessing that this information could be helpful for species beyond hake and sablefish.
Years ago @James-Thorson and Robyn Forrest were working on a project looking across regions which Jim described as follows:
integrating bottom-trawl data from non-overlapping designs, e.g.: California Current (triennial + shelf-slope), BC (many programs), Gulf of Alaska, and Eastern Bering Sea using what I call "calibration by proximity" (the assumption that survey boundaries are statistically independent of underlying biological variation)
but I don't know if it went anywhere (I don't see anything on Google Scholar).
We have submitted a paper doing this for arrowtooth using the triennial and annual bottom trawls plus BC and AFSC surveys. It's mainly focused on a global synthesis of bottom trawls survey extent. I've been calling "calibration by proximity" a regression discontinuity design to link to the stats literature on the topic. I'd be happy to chat more about it offline.
Main surveys seem like
I'd of course be happy to help with synthesis for any or all of those! Or fine to not be involved too

The surveys that we have for sablefish follow, I suspect that there may be others from DFO for other target species that are not on this list.

This method is also what Maia used to create an index of abundance, using WC, BC, and AK surveys, for the NE Pacific sablefish OM.

Main surveys seem like
- Bottom trawls
- Hook and line
- Accoustixs for hake and sardine
- Calcofi
- Juvenile rockfish
- Newport line
I'd of course be happy to help with synthesis for any or all of those! Or fine to not be involved too

I'd still love some help completing a paper doing a simulation study showing the performance of regression discontinuity designs if anyone there has time and interest. I agree it's a good path towards integrating BC and US surveys :)

More survey data are available than what is currently used within VASTWestCoast. Surveys that were mentioned on 2020-08-25 include the following:
