External carapace and pereopod exoskeleton of the Dungeness crab megalopae (a) in its undamaged form (b, c) and with dissolution presence ranging from mild (Stage 1; d) to severe (Stage 2; e, f) patterns showing similarity in the structural damages (g) or exposed crystals (h). Indicated is the scale of the measurements (μm). The undamaged megalopae originated from the offshore or northwards habitats characterized by low ∆Ωcal,60 vertical gradients, while the most severely affected megalopae came from the nearshore or coastal habitats with steep ∆Ωcal,60 conditions.

Australia bushfires contribute to big rise in global CO₂ levels in 2020

By Grahame Madge 24 January 2020 (Met Office) – A forecast of the atmospheric concentration of carbon-dioxide shows that 2020 will witness one of the largest annual rises in concentration since measurements began at Mauna Loa, in Hawaii, 1958. During the year the atmospheric concentration of CO₂ is expected to peak above 417 parts per […]
