Stratify Depths into Standard Categories

Source: R/stratify.R
stratify.Rd

Converts depth measurements in meters to standardized Pristine Seas depth strata categories using fixed thresholds for consistency across all projects.

Usage

stratify(avg_depth_m)

Arguments

avg_depth_m

Numeric vector. Average depth measurements in meters

Value

Character vector with depth stratum labels: "surface", "supershallow", "shallow", "deep", or NA

Details

Standard Pristine Seas depth strata:

  • Surface: exactly 0m

  • Supershallow: 0.1 - 6m

  • Shallow: 6.1 - 14m

  • Deep: 14.1 - 30m

  • NA: > 30m (beyond standard survey depths)

Examples

if (FALSE) { # \dontrun{
# Stratify survey depths
depths <- c(0, 3, 8, 12, 18, 25, 35)
stratify(depths)

# Use with data frame
survey_data$depth_stratum <- stratify(survey_data$avg_depth_m)
} # }
