gsw 1.1-1

• Remove a journal link that fails because of an invalid certificate.
• Fix a C function declaration that is invalid for some compilers.

gsw 1.1-0

This update is based on C code from https://github.com/TEOS-10/GSW-C (release v3.06-16-0, commit 657216dd4f5ea079b5f0e021a4163e2d26893371) and the .mat data file from https://github.com/TEOS-10/GSW-Matlab (commit 38c9635d6fd93e74c2648e4ee23cec49c1f58530). It was necessary to make some changes to the within-documentation test suite, as listed below; MRD stands for Mean Relative Difference from the values in the previous CRAN release of gsw, version 1.0-6 released 2021-07-07.

• gsw_rho_second_derivatives()$rho_SA_p: MRD 0.4
• gsw_rho_second_derivatives_wrt_enthalpy()$rho_SA_SA: MRD 1e-3
• gsw_specvol_second_derivatives()$specvol_SA_p: MRD 0.2
• gsw_specvol_second_derivatives_wrt_enthalpy()$specvol_SA_SA: MRD 3e-4
• gsw_thermobaric()$rb: MRD 0.04

gsw 1.0-7

• Update to GSW-C as of 2021-07-14, github commit bad2c9e4e154597ce563aaaf3ce09b1c52a2ab46. This does not change any existing functions in GSW-R.
• Add gsw_SP_salinometer().
• Add gsw_o2sol().
• Add gsw_o2sol_SP_pt().

gsw 1.0-6

• Update to GSW-C as of 2021-07-06, github commit 9c10670e89fce906da2cebce3399d73c054e769e.
• Remove dependency on the ‘testthat’ package.
• gsw_z_from_p() and gsw_p_from_z() gain parameters geo_strf_dyn_height and sea_surface_geopotential.
• Relax gsw_geo_strf_dyn_height() test, since values are tied to a new Matlab interpolation scheme that is not incorporated in GSW-C.

gsw 1.0-5

• Update to GSW-C 3.05-4.
• Make internal sort routines be machine-independent.

gsw 1.0-4

• Update to GSW-C 3.05-3.
• Handle NaN values better.
• Add dozens of new GSW functions.

gsw 1.0-3

• First version, using GSW version 3.03.
