More Than a Rain Gauge: When Salt Starts Steering the Sea

Simplified representation; see Figure 1.

Posted in: Ocean Sciences | Reviews & Perspectives | Ocean Science Jubilee Special Issue We usually think of ocean salinity as the ocean’s rain gauge. Rain, rivers, and melting ice freshen the surface; evaporation leaves it saltier. Seen from space, these changing patterns reveal how Earth’s water cycle is evolving, with wet regions generally becoming fresher and dry regions saltier as the cli ...[Read More]

Working with marine carbonate-system observations has taught me how much effort lies behind every row of an oceanographic dataset: long hours at sea, careful sampling, laboratory analyses, calibration and quality control. A single bottle of seawater may represent only one place, one depth and one moment, but when many such samples are brought together, they can reveal how the ocean is changing. On ...[Read More]
