The fading away feeling - I can relate. 3 and a half years watching my world shrink. But then this week - a small solar lantern casts dragonflies on the verandah table and speaks to me of emergence. For some reason I’m feeling so much more alive this week. I hope that feeling continues.

Finally, the definitive paper on the composition of the South Australian HAB has hit the preprint servers. It’s already been formally peer-reviewed. Sit down with a cuppa and have a solid read of this sobering paper.

That vaguely irritating… I can’t tell you where that sits in the scale of irritation relating to all the conspiracist β€œcauses” of this bloom. But it’s in there, somewhere in that bucket of crap.

A really wide Karenia microalgae cell, stained yellow with Lugol’s media. Its nucleus is a round red patch, centrally located in the cell. The cell is 40 microns wide and 27 microns tall, with a waistline marking the top quadrant of the cell, and a distinct node on its apex

Latest counts of Karenia in sheltered areas of the northern Yorke Peninsula are depressing. The HAB continues to growl along. 4,778 cells/mL (4.8 million cells per litre) at the Wills Creek boat ramp at Price.

Unfortunately, Bluesky is unavailable in Mississippi right now, due to a new state law that requires age verification for all users.

While intended for child safety, we think this law poses broader challenges & creates significant barriers that limit free speech & harm smaller platforms like ours.

Yes. Virtually impossible. After over five years not flying at all, I had 4 clients needing me to β€˜hop on a plane’ in the past 18 months. β€˜Hopping’ is beyond me, and the flights appalling. I hope I’ll soon be able to use my little bus to trundle off to places I’m called to in Australia, at least.

And only check out the mortalities records if you can bear it - it is horrendously sad. But the citizen science data tells us lots about the timing of the spread of the bloom, and which species were first, later, most, least affected.

Here is an updated graphic showing the 365-day running mean for the global surface temperature anomaly over the 1850-1900 IPCC pre-industrial baseline from 1941 to July 8, 2025.

I've highlighted a few key moments in the planet's recent history.

Plankton samples settling. Recent counts have included the coast from Ardrossan to Price on the Yorke Peninsula, West Lakes and Garden Island in northern Adelaide, and the Onkaparinga estuary. That Karenia mikimotoi sure gets around.

Your HABs are going to like this. I wonder how far inland the respiratory effects of a massive marine Karenia brevis bloom can penetrate?

Yesterday Jo from the ABC rang to talk about my being added to the Conservation SA β€˜Hall of Fame’ but we rapidly diverted into a chat about mangroves and saltmarshes - as you do!
The chat starts early in the show, at 7:35 minutes in, and runs to 15:58 minutes.

β€œWe are all going to die.”

True.

But not an advantageous approach to life…

and is almost always used instead of the true intended statement which is…

β€œYou are going to die, and I can’t be bothered to save you.”

It’s the name. It makes me smile. This is a tintinnid. A type of protozoan that gallops around in a wine glass. Normally not yellow - fell in a puddle of iodine stain on my microscope slide.
