See the Supplemental File "Methods_productionrates.pdf" which includes equations in-line with methods text.

Additional Funding Details:
In addition to primary funding from the NSF award OCE-1752600 additional funding was provided from The David and Lucile Packard Foundation and the North Pacific Research Board’s Graduate Student Research Award (1748-01) to Lauren Bell, PhD University of California Santa Cruz, Award title: "Fish Habitat, Fishes and Invertebrates, Lower Trophic Level Productivity Effect of substrate on herring roe response to global change."

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* File “Sitkakelps_calculated_production.rates.csv” imported into the BCO-DMO data system.
* Dates changed to ISO format
* Species list with codes and scientific names extracted from parameter information. Matched to known taxon ids using WoRMS taxa match (2022-09-06). The spelling of "Laminaria setchelii" changed to "Laminaria setchellii" with two Ls after confirming the change with the data submitter. Species list along with identifiers attached as a supplemental data table.
* Latitude and Longitude added to main data table from the provided site list.
* The following columns were rounded to four decimal places after submitter indicated that was the appropriate precision. (p g SE_g n SE_nP_dry SE_P_dry P_carbon SE_P_carbon P_nitrogen SE_P_nitrogen)
