To predict future sea level rise, we need accurate maps of the world's most remote fjords

To understand why the seabed is so important, we have to look at the glaciers themselves and what is causing them to retreat or even disappear.

Key Points: 
  • To understand why the seabed is so important, we have to look at the glaciers themselves and what is causing them to retreat or even disappear.
  • The large glaciers that meet the ocean in Greenland and Antarctica balance their mass over time largely in pace with the climate.
  • To hone our predictions, it is crucial to find the areas where warmer ocean water reaches the these glaciers.
  • This is unfortunately easier said than done, since many of these glaciers flow into some of the most remote areas of the world.

Ireland-sized glacier, Manhattan-sized icebergs

    • These ice tongues may act as a brakes on the flow of ice into the sea, slowing down mass loss.
    • In 2010, Petermann made headlines when a huge chunk broke off and formed an iceberg four times the size of Manhattan island.
    • We found the entrance was still very deep: 443 metres – as deep as the Empire State Building is tall.
    • Ryder Glacier became the target for our next expedition with icebreaker Oden in 2019.

Shielded from warmer water

    • It turned out the fjord has a prominent shallow sill in front of Ryder Glacier.
    • This sill shields the glacier from warmer subsurface Atlantic water, which appears to explain why it has behaved very differently compared to Petermann.
    • This glacier recently lost its floating ice tongue and whether or not Atlantic water makes into the fjord remains to be seen.

After Maui fires, human health risks linger in the air, water and even surviving buildings

Saturday, August 12, 2023

The fires also left lingering health risks for humans and wildlife.

Key Points: 
  • The fires also left lingering health risks for humans and wildlife.
  • When fires spread through communities, as we’ve seen more often in recent years, they burn structures that contain treated wood, plastics, paints and hazardous household wastes.
  • Lahaina and other Maui communities face similar risks ahead.

Chemical hazards in fire debris

    • Less obvious are the chemical hazards that can reach well beyond the fire zone.
    • State health officials recommended that residents wear close-toed shoes, N95 respirators, chemical resistant gloves and other protective equipment while looking through property debris.
    • When disaster debris is eventually removed by professionals, the contractors will be wearing Tyvek suits and possibly respirators to protect their health.

Buildings that didn’t burn can still have hazards

    • Particles and vapors can enter buildings through cracks, doors, windows and other portals.
    • Some of these pollutants settle onto surfaces, while others penetrate fabrics, stick to walls and enter air ducts.

Drinking water risks and soil testing

    • My colleagues and I have documented benzene levels that exceeded hazardous limits for drinking water after several previous fires.
    • These and other chemicals pose an immediate health risk to water users, even if the water smells fine.
    • Proper inspections and testing in buildings and for private wells and larger water systems are important.

Protecting waterways and aquatic life

    • Lahaina stretches along Maui’s west coast and has long been a popular site for seeing sea turtles and other marine life.
    • That sea life may now be at risk from pollutants from burned coastal buildings and runoff.
    • Communities can avoid more harmful runoff during the cleanup process by placing pollution-control barriers near storm drains, around properties and near waterways.

What happens to all the debris?

    • After the 2021 Marshall Fire in Colorado, where about 1,200 structures were destroyed, the cleanup generated 300,000 tons of waste.
    • In the process, I recommend residents reach out to public health departments for advice to help them stay healthy and safe.

Normally, I.CARE’s volunteer divers would be transplanting corals to waters off the Florida Keys this time of year, as part of a national effort to restore the Florida Reef.

Key Points: 
  • Normally, I.CARE’s volunteer divers would be transplanting corals to waters off the Florida Keys this time of year, as part of a national effort to restore the Florida Reef.
  • As water temperatures spiked in the Florida Keys, scientists from universities, coral reef restoration groups and government agencies launched a heroic effort to save the corals.
  • Divers have been in the water every day, collecting thousands of corals from ocean nurseries along the Florida Keys reef tract and moving them to cooler water and into giant tanks on land.
  • Their efforts are part of an emergency response on a scale never before seen in Florida.

The heartbeat of the reef

    • The Florida Reef has struggled for years under the pressure of overfishing, disease, storms and global warming that have decimated its live corals.
    • A massive coral restoration effort – the National Oceanic and Atmospheric Administration’s Mission: Iconic Reef – has been underway since 2019 to restore the reef with transplanted corals, particularly those most resilient to the rising temperatures.
    • Unfortunately, corals are very temperature sensitive, and the extreme ocean heat off South Florida, with some reef areas reaching temperatures in the 90s, has put them under extraordinary stress.

A MASH unit for corals

    • This year, the Florida Keys reached an alert level 2, indicating extreme risk of bleaching, about six weeks earlier than normal.
    • At the Keys Marine Laboratory, scientists and trained volunteers have dropped off thousands of coral fragments collected from heat-threatened offshore nurseries.

Protecting corals still in the ocean

    • I.CARE co-founder Kylie Smith, a coral reef ecologist and a former student of mine in marine sciences, discovered a few years ago that coral transplants with large amounts of fleshy algae around them were more likely to bleach during times of elevated temperature.
    • Removing that algae may give corals a better chance of survival.
    • Smith’s group typically works with local dive operators to train recreational divers to assist in transplanting and maintaining coral fragments in an effort to restore the reefs of Islamorada.

Monitoring for corals at risk

    • To help spot corals in trouble, volunteer divers are also being trained as reef observers through Mote Marine Lab’s BleachWatch program.
    • The lab is training them to recognize bleached, diseased and dead corals of different species and then use an online portal to submit bleach reports across the entire Florida Reef.

Rebuilding the reef

    • Through careful analysis of the species, genotypes and reef locations experiencing bleaching, scientists and practitioners are learn valuable information as they work to protect and rebuild a more resilient coral reef for the future.
    • That is what gives hope to Smith, Lewis, Nedimyer and hundreds of others who believe this coral reef is worth saving.

'Your first emotion is panic': rips cause many beach drownings, but we can learn from the survivors

Wednesday, August 9, 2023

Yet, unlike other well understood and feared natural hazards such as bushfires and floods, the ever-present menace of rip currents is often overlooked.

Key Points: 
  • Yet, unlike other well understood and feared natural hazards such as bushfires and floods, the ever-present menace of rip currents is often overlooked.
  • Until now, the firsthand effects of rips on the people caught in them had also been overlooked.
  • Research concentrated more on physical characteristics of the hazard, such as flow dynamics and types of rips.

Many survivors were naive about the risks

    • Many interviewees had been naive and unprepared for encountering a rip.
    • We just basically ran into the water, as you do when you arrive at the beach, you throw down the towel, and we just raced into the water.

What is being caught in a rip like?

    • Once caught in the rip’s grip, panic was a very common response, leading to a mental “fog” that hampered decision-making.
    • Even if you know what to do it’s hard to put that into action when you’re actually in the rip […] because your first emotion is panic.
    • Even if you know what to do it’s hard to put that into action when you’re actually in the rip […] because your first emotion is panic.
    • Once you understand rips, I think the fear of them disappears because you can use a rip to your advantage.
    • Once you understand rips, I think the fear of them disappears because you can use a rip to your advantage.

What are the lessons for surviving rips?

    • I certainly all these years have never really truly appreciated the enormity of a rip until I got caught into one.
    • Most of us learn from our experience, and I think you have to experience things before you appreciate the reality of them.
    • I certainly all these years have never really truly appreciated the enormity of a rip until I got caught into one.
    • These prompts could guide them to make the best escape decisions and resist panic that could cloud their judgement.
    • Signs could be placed on the beach, providing simple, clear messages such as “REMAIN CALM” if caught in a rip.
