Coastal trapped waves carry sea level, temperature and nutrient signals thousands of kilometres along coastlines — the ocean's long-distance phone line.

Reefs are joined by currents into a living network. How connectivity works, why stepping stones matter, and how it shapes marine reserves and kelp restoration.

How oceanographers measure seawater pH and alkalinity, why it's harder than it looks, the sensor zoo from Argo floats to moorings, and what the numbers mean.

Mesoscale eddies — the ocean's weather systems — shuttle nutrients and larvae across continental shelves. How they form, how they're seen, why kelp cares.
Dr. Lena Fischer ·
The ocean's mixed layer — its wind-stirred surface engine — sets how much light plankton see and when deep nutrients return. How mixed layer depth works and why it matters.
Dr. Lena Fischer ·
Ocean fronts — the sharp boundaries where different water masses collide — concentrate plankton, baitfish and predators into living lines. Here's why they matter.

Five vast gyres turn like slow wheels in every ocean basin, shaping currents, climate and where plastic gathers. Here's how ocean gyres actually work.

Significant wave height, swell period, direction, water temperature — learn to decode ocean buoy reports like a waterman and plan safer, better days on the sea.

How satellites derive sea surface temperature from infrared and microwave radiometers, why clouds and fog mask kelp coasts, and how scientists validate SST.

Thermoclines, haloclines and pycnoclines are the invisible boundaries that slice the sea into layers. What they are, how they form, and why they run coastal life.

Underwater, sound is the only sense that travels. How sound speed works in seawater, what the SOFAR channel is, and why the ocean is far noisier than it seems.

Every great kelp forest sits in the shadow of a great current. Here's how western and eastern boundary currents shape temperature, nutrients and the world's temperate reefs.

Wind blows, water turns ninety degrees. The gentle physics of Ekman transport — the spiral beneath the surface, coastal upwelling, gyre hills and spills.
Dr. Lena Fischer ·
Kelp canopies don't just slow water — they reorganise it. How canopy flow physics shapes turbulence, nutrient delivery and life inside a kelp forest.

Follow kelp carbon from frond to terminus: grazing, decomposition, export, burial, and deep-sea pathways — and the tracing science that reveals the routes.

A deep dive into upwelling physics: Ekman transport, the world's great upwelling systems, how scientists track them from space, and what climate change does.
