This reproducible R Markdown analysis was created with workflowr (version 1.7.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.


Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.

The command set.seed(20210113) was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.

Great job! Recording the operating system, R version, and package versions is critical for reproducibility.

Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.

Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.

The results in this page were generated with repository version ba71c79. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:


Ignored files:
    Ignored:    .Rhistory
    Ignored:    .Rproj.user/

Unstaged changes:
    Modified:   code/Workflowr_project_managment.R
    Modified:   data/overview/overview_files.csv
    Modified:   data/regions/RECCAP2_region_masks_all_clean.cvs

Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.


These are the previous versions of the repository in which changes were made to the R Markdown (analysis/regions.Rmd) and HTML (docs/regions.html) files.

1 Overview

Three region mask files prepared by Luke Gregor for the analysis within RECCAP2-ocean are available:

  1. RECCAP2_region_masks_all.nc
  2. RECCAP2_openocean_1deg.nc
  3. RECCAP2_coastal_MARCAT_1deg.nc

Please note that the content of 2. an 3. should be identical to the fields open_ocean and coastal_MARCAT contained in 3. Accordingly, files 2. and 3. are not required for the analysis. In the following, I plot the content of 1.

For the submission, spatially resolved surface fluxes of CO2 should be integrated across the entire open_ocean region for fco2_glob, and across the indices 1-5 of the open_ocean region for fco2_reg,

2 File: region_masks_all

2.1 Seamask

Please note that the seamask provided within 3. is not identical to the open_ocean region and should not be used for data analysis.

region_masks_all <-
  read_ncdf(paste(path_basin_mask, "RECCAP2_region_masks_all_v20221025.nc", sep = "")) %>%
  as_tibble()

region_masks_all <- region_masks_all %>%
  mutate(seamask = as.factor(seamask))

region_masks_all %>%
  ggplot(aes(lon, lat, fill = seamask)) +
  geom_raster() +
  coord_quickmap(expand = 0)

2.2 Regions

Below, the open ocean regions used to calculate fgco2_reg are displayed. Please note that the coastal_marcats regions is covered by the other regions.

region_masks_all_seamask <- region_masks_all %>%
  select(lat, lon, seamask)

region_masks_all <- region_masks_all %>%
  select(-seamask)

region_masks_all <- region_masks_all %>%
  pivot_longer(open_ocean:southern,
               names_to = "region",
               values_to = "value") %>%
  mutate(value = as.factor(value))

region_masks_all %>%
  filter(value != 0) %>%
  ggplot(aes(lon, lat, fill = region)) +
  geom_raster() +
  scale_fill_brewer(palette = "Dark2") +
  coord_quickmap(expand = 0)

2.3 Sub-regions

Each open ocean region consists of several subregions with indices for further regionalization.

region_masks_all %>%
  filter(value != 0) %>%
  group_split(region) %>%
  map(
    ~ ggplot() +
      geom_raster(data = region_masks_all_seamask %>% filter(seamask == 0),
                  aes(lon, lat)) +
      geom_raster(data = .x,
                  aes(lon, lat, fill = value)) +
      coord_quickmap(expand = 0) +
      labs(title = paste("region:", unique(.x$region)))
