چکیده
the authors present new data on Mytilus edulis shells REY content and fractionation as a potential proxy for REY content in seawater. The potential impact of pH and temperature on such REY signal in the mussel shells is investigated, as well as the potential process of shells REY incorporation. Part of the paper also deals with shell preparation and analytical procedures for analyses of such low-concentrated elements. The overall quality of this paper sounds good to me and the subject is in the scope of BG. Title and abstract reflect well the manuscript content and I have no problem with the presentation, figure quality/number and language. The figure legends should be more precise in general. Information is missing there for the figures to be self-standing. I do however have scientific concerns, which need to be addressed in my point, mainly in the discussion part that might need some re organisation and more discussions on some points. These are detailed below.

some of the isotope and elemental work previously done on M. edulis. Missing some of the relevant and primary literature on M. edulis is exemplified in quantitative temperature and/or pH proxy, the impact of the EPF and other vital effects needs to be assessed, like by studying M. edulis mussels cultured under controlled pH and temperature conditions.” Although the below studies did not explore...

in seawater. We present a new protocol for sample preparation and determination of REY concentrations in bivalve shells, that includes sample treatment with NaOCl followed by REY separation and preconcentration. The data obtained was further used to calculate REY partition coefficients between shells of M. edulis and ambient seawater, and acquired results were then used in the investigation of ...

Mussel shells are potential bioarchives of proxies for changes in the physicochemical conditions in the bivalve’s habitat. One such proxy is the distribution of rare earths and yttrium (REY) in seawater, as REY speciation in seawater is sensitive to pH and temperature variations, due to the impact of these parameters on the activity of CO 3 in seawater. We present a new protocol for sample prep...
