Come do a PhD with us at Bristol! Looking for a student to look at B incorporation into silica - both experimentally-precipitated and biogenic.. With @krhendry.bsky.social @sophwestacott.bsky.social and Franziska Stamm. Deadline Monday 13th of January! DM or email me for more details. bit.ly/3W8WshH
Ground-truthing the boron isotope-pH proxy in biogenic silica — NERC GW4+

We use boron isotopes in diatoms to constrain pH change in the N Pacific during the iNHG 2.7 million years ago🧪⚒️🌊
Carbon Cycle and Circulation Change in the North Pacific Ocean at the Initiation of Northern Hemisphere Glaciation Constrained by Boron‐Based Proxies in Diatoms
δ11B and [B] in diatom frustules reveal a surface water increase of 0.3–0.5 pH units in the subarctic Pacific Ocean over the iNHG These changes would have lowered atmospheric pCO2 and contributed...

New paper! First global compilation of 71 oxygen isotope records of diatom silica from lake sediments. Key point - distinct Holocene climate signals, showing that the proxy can be used as a robust palaeoclimate tool @meljleng.bsky.social @geaswann.bsky.social
