Coastal erosion and human intervention
A rapidly escalating volume of traffic on ocean beaches

"In the absence of the Bribie buffer and without the dune system on the surf coast, they would suddenly be exposed to storm surge and inundation."

"Morton says the previous government long ignored the erosion under the assumption this was “mother nature” at work. But the new MP says the review will consider the impacts of human intervention, from dredging and wake from the offshore shipping channel to widespread coastal development."

"Bribie Island resident, retired engineer and environmental volunteer John Oxenford agrees human intervention has fuelled the erosion – but he points to the 2007 opening of the beach to four-wheel drives as “opening a real Pandora’s box”."

"The pressure of tens of thousands of vehicles and associated foot traffic since had prevented the natural regrowth of dunes during the winter period, and further exposed them to erosion during the summer months, he says.“Year over year over year, we’ve seen rapidly escalating volume of traffic on the ocean beach,” he says. “The end result of that is erosion.” "

I saw this book on another post - and so went and found a copy at a 2nd hand book shop…
Looking forward to lunches at work with a cup of tea and maybe a couple of rainy Sundays at home…

Thawing Permafrost Primes Slumps

As permafrost thaws on Arctic hillsides and shorelines, the land often deforms in a unique fashion, known as a slump. Formally known as mega retrogressive thaw slumps, these areas superficially resemble a landslide. They’re also prone to repeat performances: as many as 90% of Canada’s Arctic slumps recur in the same place as previous slumps. Researchers used ground-penetrating radar and other tools to study the underground structure at slumps and found that several factors contribute to this repetitive cycle.

Seawater soaking into the foot of a hilly shore can destabilize the permafrost, creating a slump. That changes the nearby ground cover, exposing more permafrost to warming; their measurements showed this warming could extend tens of meters underground, priming the area for future slumps. Similarly, the mudslides and narrow ravines that form on an active slump also shift away ground cover and warm the underlying permafrost. Together, these factors suggest that once a slump forms, more slumps will occur as the underlying permafrost warms. (Image credit: M. Krautblatter; research credit: M. Krautblatter et al.; via Eos)

I loved this scenic view in Capitol Reef National Park because of all the layers of flora and rock formations from a foreground of shrubs and grasses to distant background red rock cliffs. The scene shows the rugged beauty of the desert environment.

Rugged cliffs in Capitol Reef National Park rise dramatically to contrast with the sky’s delicate wispy clouds. Early morning light highlights the multiple layers of sedimentary rock that record 200 million years of geologic history. Processed in black and white.

“Visions in Ice”

The glittering blue interior of an ice cave sparkles in this award-winning image by photographer Yasmin Namini. The cave is underneath Iceland’s Vatnajokull Glacier. Notice the deep scallops carved into the lower wall. This shape is common in melting and dissolution processes. It is unavoidable for flat surfaces exposed to a melting/dissolving flow.

Fluvial System Block Diagrams
--
I was looking to understand a fluvial system the other day, up in the high Arctic, as I looked at 3DEP remote sensed elevation data… I have always been fascinated by the how geology, water, weather shapes a landscape, including erosion (aka geomorphology if you will) – and realized how very much value fluvial block diagrams have as we try to conceptualise what has, is and will happen(ed.)

Contractors need to be held accountable for mindless cutting of trees.

Contact SKANSKA and tell them that you are outraged that they cut a grove trees without permission, causing erosion and flooding.

Contractors need to be held accountable and heavily fined.

Lifeless rock pools at Sawtell

After cyclone Alfred whipped up a 'bacteria smoothy' along Australia's east coast the sea foam then merged with a 'flush' from the suburbs. Dislodged smelly sponges at Sawtell beach made breathing and contact impossible. Even without fossil fueled disasters the intertidal zone at the north end of the beach is barren. The rock pools and crevices no longer house sea anemones, crabs, black nerites, limpets, sea stars, mulberry oyster borers, algae, sea anemones, sponges, tube worms, sea stars, oysters, and fish.

Still good enough for hosting 'sports' and advertising events amplified by megaphone so they can be heard at Lord Howe Island too.
