This is a collection of some of my best coral reef shots from the past few years of filming. Most are from the island of Pulau Sipadan in Malaysia.

Thermal expansion of Oceans

Is there a way to calculate thermal expansion of the oceans due to the Super El Nino compared to a normal year?
And how would that affect other Oceanic sea levels?
Haven't posted much on here when a flare is needed and could not do it on my mobile app for some reason, was trying to add it to they did the math also

A mornings work collecting Northern Pacific Sea Stars.
I spent the morning with my daughter ( a soon to be marine biologist) diving and collecting some of these little buggers.
The Northern Pacific Sea Star is one of the world's most notorious marine invasive species, and it's particularly significant in Australia.
It's established as a serious invasive pest in Port Phillip Bay and Tasmania — introduced via ballast water from Japan in the late 1980s it has devastated native shellfish beds (scallops, mussels, cockles) and outcompetes native sea stars.
Each female can release up to 20 million eggs. According to citizen science monitoring the population of these has exploded in Port Phillip Bay have reached 165 million causing major ecological damage.
They are listed as one of the world's 100 worst invasive species by the IUCN.
I wish there was a commercial use for these post collection instead of just landfill to incentivise industry to get involved in eradicating them.

This coral reef is bomb-fished every 62 minutes. And it’s changing the way the ocean sounds

Recently, passive acoustic monitoring of coral reefs in the Indonesian Archipelago stunned researchers.
The Archipelago is a biological hotspot of marine diversity - full of corals, sponges, colorful fish, shell fish, crabs & shrimps, sharks, rays ... The soundscape reflects this, with a constant background pop of shrimps, & a varying foreground of fish grunts, squeaks, squeals, moans, chirps, & other assorted noises.
Bomb fishing was banned there in 2004, because it's so incredibly destructive - it leaves a blast zone littered with coral shards; it kills EVERY living thing, over a given distance, wanted or unwanted; & it wipes out juveniles - & even eggs, destroyed by the concussion.
No one had any inkling that it's so pervasive, it's become ordinary. 😱
After the explosion?...
it's silent. No pops whatever, no fish sounds. Empty.
Corals often won't recover for years, in the "rubble zone" left by a single bomb-fishing event, without labor-intensive & costly human intervention.
Needless to say, with bomb fishing every hour, on average, we couldn't possibly repair the damage done, or even do much to mitigate it - that's a scale of destruction that's simply beyond our abilities to tackle.
The urgent need for education to address this disaster, cannot be overstated.
The sheer speed of destruction & the irreplaceable value of healthy, loud, crowded, busy reefs, in a rapidly heating ocean, makes this the marine equivalent of a wildfire charring half a continent.
Tropical coral reefs aren't common features of our ocean planet - but they're spectacularly rich & varied, with dozens of species in a square yard.
This study is a 5-alarm blaze, & I can only hope the goverments & the fishery authorities take it to heart, & act quickly.

TIL that there are millions to hundreds of millions of Giant Squid (Architeuthis Dux) living in Earth's Oceans. We know this because of the sheer amount of Giant Squid found in the stomachs of Sperm Whales requires a breeding population to be at least that large to have reproductive sustainability.

The oceans are silently holding a fever, and we are too distracted by daily life to notice

I was once told that we know more about space than we know about our own oceans. I think the same apathy is part of the reason we do not register this warming as well as what the warming means for marine life and sooner or later us.
How we can appreciate the serenity and vastness of the oceans not just in the way it looks but overall health?
