v3.4-1

coldpool 3.4-1 (August 22, 2024)

NEW FEATURES

• Added temperature isotherm extent as built-in data sets for
  the NBS (see ?nbs_mean_temperature).

DATA UPDATE

• Update with 2024 survey data.

v3.3-1

coldpool 3.3-1 (February 23, 2023)

NEW FEATURES

• Added kriging_cv() function to compare kriging methods
  using cross-validation for ordinary kriging,co-kriging, and
  regression kriging.
• Added estimate_z_expansion() function to estimate the vertical
  expansion factors for 3D kriging based on cross-validation.
• Added estimate_anisotropy() function for estimating 2D
  anisotropy in variograms using cross-validation.
• Added new file naming conventions and masking options to
  interpolate_variable(), which should deprecate data2raster()
  in a future release.

v3.2-1: Finalized 2023 EBS and NBS data

This package update to version 3.2-1 includes finalized 2023 northern Bering Sea (EBS) data and data products. Finalized 2023 eastern Bering Sea (EBS) shelf data products were provided in the prior update (coldpool version 3.1-1).

Update:

• Finalized bottom and surface temperature data from the 2023 NBS bottom trawl survey (ebs_nbs_temperature_full_area.csv).
• Finalized 2023 data products for the NBS and combined EBS+NBS (built-in data sets).
• New figures showing 2023 data products for the NBS and combined EBS+NBS (plots directory).

v3.1-1

BUG FIX

Modified interpolate_variable to accept sf objects as an argument to select.region. Enables production of temperature products with a user-defined extent and matches functionality from prior to the switch from rgdal/raster/sp to terra/sf. Example: https://github.com/afsc-gap-products/coldpool/blob/main/analysis/roms_level3_coldpool_part2.R

v3.0-1: Preliminary 2023 update

Preliminary update for 2023 that includes:

• 2023 EBS temperature products.
• Provisional NBS bottom temperature (no NBS surface temperature).
• New annual bottom temperature plots to /plots/annual_bt.
• Replacement of old raster package functionality with functions from the terra package.

The package and data products will be updated again once NBS data are finalized (by the end of September 2023).

v2.2-2

Minor fix to remove plyr from depends

2.2: Interpolate to a raster stack

Added new functions provided by @kakearney to facilitate comparison between coldpool data products and Bering10K output.

New functions:

• data2raster(): interpolates and mask variable to a raster stack using a user-specified interpolation method.
• calcindicies_temp(): Calculates temperature indices from a .csv file.
• parseregion(): Handles CRS transformation (w/ sf::st_transform) or retrieval of bottom trawl survey shapefiles (w/ akgfmaps::get_base_layers).

2.1: 2022 Finalized NBS

This update includes finalized 2022 northern Bering Sea (EBS) data and data products. Finalized 2022 eastern Bering Sea (EBS) shelf data products were provided in the prior update (coldpool version 2.1).

Update:

• Finalized bottom and surface temperature data from the 2022 NBS bottom trawl survey (ebs_nbs_temperature_full_area.csv).
• Finalized 2022 data products for the NBS and combined EBS+NBS (built-in data sets).
• New figures showing 2022 data products for the NBS and combined EBS+NBS (plots directory).

2.0: 2022 Update

This update includes the 2022 EBS shelf bottom trawl survey temperature data products and preliminary 2022 NBS data products. NBS data products will be finalized in mid-September.

Update:

• New bottom and surface temperature data from the 2022 EBS shelf bottom trawl survey.
• Preliminary bottom and surface temperature data from the 2022 NBS bottom trawl survey (to be updated and finalized in mid-September 2022)
• Updated 2022 data products for the EBS shelf (mean bottom temperature, mean surface temperature, cold pool area, temperature for strata < 100 m) and preliminary data products for the NBS and EBS+NBS.
• New figures showing 2022 temperature data for the EBS and preliminary figures for the NBS and EBS+NBS.

1.4

Added deprecated historical data sets to built in data:

• Stratum-area weighted mean bottom and surface temperatures for EBS shelf standard and standard+PlusNW
• Stratum-area weighted mean bottom and surface temperatures for the NBS
• Mean bottom and surface temperatures from EBS hauls conducted at bottom depths < 100 m.
