#' Atlantic core-top foram assemblages
#'
#' A dataset containing over 1000 foram assemblages from the Atlantic from
#' Kucera et al (2005) and the 50m SST for the warmest season. Rare taxa and
#' co-located assemblages are removed.

#' @format A data frame with 1093 rows and 33 variables.

#' @title Storsandsvatnet
#' @description Storsandsvatnet is a lake in western Norway. From the sediments
#' a core was obtained, and 11 samples was submitted for radiocarbon dating.
#' The data contain the depths of the slides dated and the younger and older
#' calibrated ages for each slide.
#' @format
#'  A data.frame with 11 observations on the following 4 variables.
#'    \describe{
#'        \item{depthup}{The upper border of the dated slide}
#'        \item{depthdo}{The lower border of the dated slide}
#'        \item{cageup}{The younger calibrated age of the dated slide}
#'        \item{cagedo}{The older calibrated age of the dated slide}
#'        }
#' @details  The calibrated ages is obtained by calibration of the radiocarbon
#' dates.
#' The borders represent mean calibrated age +/- 1 SD of calibrated age.
#' @source The data are unpublished and provided by H. John B. Birks
