Interactive comment on “Ecosystem regimes and responses in a coupled ancient lake system from MIS 5b to present: the diatom record of lakes

Cvetkoska et al. present a diatom record of high quality, alongside various geochemical proxies, from a c. 92ka lake sediment sequence retrieved from Lake Ohrid (part of the SCOPSCO project). The main purpose of the research is to compare this record to a previously published diatom record from the adjacent Lake Prespa (to which Ohrid is hydrologically connected) in order to compare system resistance and resilience to past climate change and to investigate the potential for Prespa to influence change in Ohrid. In my view there are four substantive issues which the authors are invited to consider relating to the interpretation of the data (detailed below). This is followed by a list of specific queries / suggested changes. In addition, the manuscript would benefit from another round of proof reading to improve the clarity of prose.
