QuestionsCategory: QuestionsWhat 18O indicators are there besides foraminifera?
Clean Harbors Staff asked 3 months ago

It is now standard practice to use foraminifera to represent paleo 18O signatures from a marine system. However, there are some problems if you want to show 18O variations in the last 100 years using foraminifera. One such problem is, for example, low sedimentation rate, growth in the stratification of a water column etc.

Therefore, I wonder if there are any biological or geological indicators that can be used to show the change in the 18O signature of a marine system in recent times (since 1880)?
