Dawn on Tasmania's east coast: four divers, two hammers, and a barren the size of a football pitch. What an urchin cull actually looks like from inside the vis.

Howe Sound recovered from a century of industrial pollution to glass sponge reefs, returning orcas and thickening bull kelp — an atlas guide to BC's comeback fjord.
Dr. Mara Ellison ·
Beneath every kelp forest sleeps an invisible reserve of microscopic filaments. How gametophyte seed banks form, persist and wake — the forest's hidden memory.
Dr. Theo Nakamura ·
Genetic rescue moves genes into a struggling kelp population to restore diversity and fitness. How it works, when it helps, and when it backfires.
Dr. Elias Brandt ·
Kelp forests run on an annual clock of light, temperature and nutrients. Learn how kelp phenology works, why it's shifting, and why timing runs restoration.
Dr. Theo Nakamura ·
How scientists read the family tree of a kelp forest — from SNP chips to seascape genomics — and what genetic maps reveal about provenance and adaptation.
Dr. Elias Brandt ·
A kelp seed bank is a genetics program, not a freezer. Provenance, diversity targets, collection design and rotation — managing seedstock for resilient kelp.
Dr. Elias Brandt ·
Kelp forests travel one microscopic spore at a time. How far spores really go, what decides where they settle, and why dispersal shapes every restoration plan.
Dr. Mara Ellison ·
Most kelp spores settle metres from their parents, but a rare few travel kilometres — and rafts cross oceans. What dispersal distances mean for connectivity and restoration.
Dr. Elias Brandt ·
Hunted to near-collapse, the pinto abalone is being rebuilt by hatcheries and divers in the Salish Sea. Inside North America's meticulous abalone comeback.
Dr. Mara Ellison ·
How seagrass restoration earns carbon credits: the methodologies that exist, how sediment carbon is measured, permanence risks, and what buyers should ask.
Priya Raman ·
Kelp forests, seagrass meadows and estuaries trade food, animals and larvae across the coastal mosaic. Why connectivity — not patch size — decides resilience.
Dr. Mara Ellison ·
Sonoma's coast lost most of its bull kelp a decade ago. A guide to the collapse, the abalone closure, and where the forest is quietly returning.
Jack Callum ·
Sydney lost its crayweed forests to sewage in the 1980s — then brought them back. A guide to the city's kelp, golden kelp meadows and dive reefs.
Dr. Mara Ellison ·
Turf-forming algae are the low, weedy mats that move in when kelp forests fall — and can hold a reef in place. A group profile of the kelp forest's most stubborn rival.
Dr. Theo Nakamura ·
Light is kelp's only real ceiling. How seawater absorbs and scatters sunlight, what sets kelp's depth limit, and why water clarity is a restoration variable.
Dr. Lena Fischer ·
The white abalone crashed so fast that by the time it was protected, wild adults were too far apart to breed. Captive breeding is testing a way back.
Dr. Theo Nakamura ·
Black abalone once blanketed California's rocky intertidal, then disease and poaching erased most of them. Inside an unlikely marine recovery story.
Dr. Mara Ellison ·
Environmental DNA lets scientists census a kelp forest from a few litres of seawater. How eDNA surveys work, what they miss, and why they matter.

A Tidewright field note from California's north coast: two weeks inside a purple urchin barren, counting what kelp loss looks like and planning its way back.

Marine conservation careers span rangers, policy staff, restoration crews and data scientists. Here is an honest map of the routes in, the pay, and the skills that matter.
Dr. Mara Ellison ·
A field note from the Mendocino coast: the morning sonar and diver eyes confirmed bull kelp canopy over our first seeded corridor, and what that number means.

The purple sea urchin turned patches of California kelp forest into barrens. Learn its biology, its hidden hunger, and why it is both villain and victim.
Dr. Mara Ellison ·
Every autumn we weigh the urchins culled from the barren edge at Boomer Bay. This year the scales told a different story — and changed next year's plan.
Jack Callum ·
Urchin barrens can persist for decades even when kelp conditions return. Why barrens behave as an alternative stable state — and how reefs flip back.

Moving warm-tolerant kelp genotypes ahead of climate heat could buy forests decades. Here's the evidence, the ecological risks and the protocols that make it safer.
Dr. Elias Brandt ·
Kelp survived the ice ages in pockets called glacial refugia. That history still structures the genetics of today's forests — and guides restoration.
Dr. Elias Brandt ·
Once a year we swab restored and wild kelp beds across Tasmania for the provenance program. Two hundred blades, five sites, and what the lab read in them.
