δ18O to Temperature Converter
This tool converts carbonate δ18O data to temperatures. It automates the process of applying a number of correction methods which have been developed in the literature, as well as providing convenient access to a range of published species- and scenario-specific calibrations. It also automates two routine but technically complex tasks: performing paleocoordinate rotations and reconciling age datums between required datasets.

The tool output also includes a short summary of the methods used for each run, with citations. This information may be used in publications using this tool, in whole, in part, or in adaptation, subject to the journal’s standards. (At a minimum you should cite the references listed in order to give credit to the authors of the underlying datasets and methods used.)
BioDeepTime
Humans have profoundly modified ecosystems and planetary processes across the globe. Yet it remains difficult to quantify humanity’s impact because doing so requires disentangling human and natural drivers of change. The BioDeepTime Project aims to unravel the drivers of biodiversity dynamics by leveraging the combined power of ecological and fossil timeseries and by advancing broadly integrative theories of biodiversity change and scaling in time.

Endless Forams
Planktonic foraminifera are marine mixotrophic protists that are widely used to reconstruct past oceans and climates, due to the abundant fossil record of their calcite tests throughout much of the world’s ocean. They also are a focal taxa for studies of biology, ecology, and evolution for the same reason. One of the difficulties encountered by researchers in using this clade is the high standing morphological variability within species. Often it is difficult to decide if an individual contains the characters that define one species versus the next. Much of this difficulty arises because there simply are not enough examples of what each species looks like. This website is aimed at changing that by providing abundant examples of what each planktonic foraminifera species looks like.
