Worked solutions for the held Oxford second-year Earth Sciences examination of 1 June 2023. Source release: https://www.whatdotheyknow.com/request/earth_science_past_papers_and_ex/response/3419815/attach/4/Papers.zip?cookie_passthrough=1[released question paper and Attachments A and B]. The examination asks candidates to choose one question from each of six sections; every available numbered alternative is addressed here. These are derived solutions, with no question statements reproduced.
\b[Source gap: Attachment C, referenced for Question 9, is absent from the held release.] The printed summary table permits numerical calculations, but parts 9(d–e) remain explicitly provisional until that attachment and any conventions it supplied are checked. Attachments A and B are available and are treated as supporting material for Questions 3 and 4. Image positions below use fractions of the map frame, excluding page margins. The repeated salt-velocity subscript in Question 6 and the circular reference in Question 10 are documented where they affect the solution.
