Douglas, [email protected] Additional documentation for the Diatom record in Lake C2: Objetives Methods Results Interpretation and Conclusions WebThis diatom, as well as Hannaea arcus, was found in the main stream flowing into Lake C2. Both taxa are characterized as lotic or rheophilous diatoms. They are present throughout the core's profile, i.e., during the marine and freshwater conditions. Their presence can be used to track river flow and input into the lake. how to change counter top
