Sharks – Michael Muller

Sharks - Michael Muller
Sharks – Michael Muller

Michael Muller is probably best known for his work as a portrait photographer (focusing on celebrity subjects). He also has, it turns out, a longstanding fascination with sharks. While working as a commercial photographer for Speedo, Muller designed and built a waterproof housing for his 1,200 watt studio strobe lights. Incredibly, he takes these lights underwater – assisted by two to six divers and at least one person on the boat – and has spent a couple of years travelling the world to photograph sharks. 

The resulting photos, of bull, tiger, white, hammerhead and several other species of shark, are fascinating. They are unlike any shark photographs I have seen before, with a cinematic quality and the intensely unusual property – for most underwater photos – of being filled with light. Sharks swim out of bright white light towards the camera, and many of the images are deliberately over-exposed, heightening the dramatic effect. The jump from having professional-quality camera strobes to essentially a full studio lighting rig underwater is enormous, and the results are visually stunning.

Muller’s pictures, to me, emphasise the otherness of sharks. They do not look like cuddly, approachable (although in many cases Muller went very, very close to his subjects) or easy to fathom animals. I like this. Some approaches to conservation try to emphasise how sharks do not intend harm, and attempt to demystify them, with the aim of making them comprehensible and thus worthy of protection. The genre of photography that shows divers and sharks apparently harmoniously inhabiting the watery realm is invariably more about the humans than it is about sharks. That criticism cannot be levelled at these images.

The final sections of the book contain a species guide, essays about shark ecology and conservation, and technical information about the photographic equipment and shot set up. Some of the shark biology and conservation information was contributed by Capetonian shark conservation biologist Alison Kock, who put False Bay’s white sharks on the scientific map.

You can preview some of the images from the book here, and an interview with Muller here. The Washington Post and Wired have image-rich features on this project, too.

This is an enormous book (standard Taschen fare). You’re going to need a bigger bookshelf (a joke about this book which has no doubt been made forty times – I apologise). You can get a copy here (South Africa), here or here.

Ice Blink: The Tragic Fate of Sir John Franklin’s Lost Polar Expedition – Scott Cookman

Ice Blink
Ice Blink

In Ice Blink, Scott Cookman provides another account of the much-reported final expedition of Sir John Franklin to the Canadian Arctic, in search of a Northwest Passage. The story has been told many times, in many ways, and Cookman’s rendition is gripping.

Several theories have been advanced to account for the failure of any members of Franklin’s expedition to return. A few bodies have been found, and eyewitness accounts from Inuits in the areas that the Erebus and Terror were trapped in the ice provide some clues as to what happened. A conclusive explanation, however, has not been found.

Cookman advances the idea the the men were killed by botulinium toxin, introduced into their diets from poorly prepared tinned food.  He is dogmatic about this theory to the exclusion of all others, and at times makes it sound misleadingly certain that this was the cause of the disaster. In fact, experts fail to agree on what killed the men; other theories include lead poisoning (from the canned food), or simply just the cold and poor preparation.

I would recommend you read this book after you’ve familiarised yourself with some of the other literature about Arctic exploration and Sir John Franklin in particular, and are equipped to separate fact from hypothesis. If you’re interested in the subject, may I strongly recommend The Man Who Ate His Boots and Frozen in Time.

You can read the first chapter of the book here and a New York Times review here.

Bookshelf: Climate Change

Climate Change: Briefings from Southern Africa – Bob Scholes, Mary Scholes & Mike Lucas

Climate Change
Climate Change

This is the book on climate change that I never knew I needed. It is written in the form of 55 questions and answers, from a South African perspective. One of the three authors (Dr Mike Lucas) is a biological oceanographer, so there is ample information on the effect of climate change on the marine environment. The other two authors are climate change specialists.

The book is well illustrated with photographs and diagrams. The authors address sea level rise, El Niño, water scarcity, the effect of rising temperatures on the Southern Ocean and Antarctic, and the survival of coral reefs, among other topics. The final few questions deal specifically with practical actions that can be taken to adapt to and (perhaps) avoid climate change, and one’s personal carbon footprint.

You don’t have to be a weather nerd to benefit and learn from this book. I encourage you to seek it out.

Bookshelf: Blue Mind

Blue Mind – Wallace J. Nichols

Blue Mind
Blue Mind

In Blue Mind, biologist (turtle researcher) Wallace J. Nichols articulates and elaborates upon an idea you’ve probably already had all on your own: that being close to water is good for you. More precisely, Nichols is interested in what proximity to water does for our brains. In this book he presents scientific evidence for the salutary effects of water on humans, but does not shy away from anecdote. His tone is vigorously optimistic.

I don’t need to look very far to see evidence of Nichols’s hypothesis: Waves for Change teaches youngsters from violent communities in Cape Town to surf, and in the process effects an almost miraculous change in their lives. (They deserve your support.) Nichols also says that he can see a change – a warming – in people’s body language when they enter an aquarium. I spend enough time at the Two Oceans Aquarium that I should have an opinion on this, but I don’t, so I need to look more closely.

I admit that this book is on the fringe of what I would usually read – it is what I would usually dismiss as touchy-feely pop psychology – but I do think Nichols is on to something (and here I am in very excellent company). He holds a Blue Mind Summit every year, bringing together neuroscientists, artists and conservationists to discuss the ocean and the brain, and how to use insights about water’s powers for good.

Read a review at The Guardian, and an interview with Nichols at Outside Magazine. For the extra curious, read a quite a detailed profile of Nichols, also at Outside Magazine.

Newsletter: Making friends

Hi divers

Weekend dive plans

Saturday: Double tank dive at 7.30am launching from Simon’s Town jetty

Sunday: Double tank dive at 7.30am launching from Simon’s Town jetty

I’ve been out several times this week and we’ve found clean, green and brown water in False Bay during this week’s dives. We’ll do double tank dives on both days of the weekend, starting early. I haven’t picked sites for the weekend as we will go looking for clean water when we launch. If you want to be on board, you know what to do.

Cold – Ranulph Fiennes

Cold
Cold

I have been lax with book posts lately, but hope to remedy that in fairly short order (sorry for you!). This book, Cold by famed British explorer Ranulph Fiennes (not to be confused with Lord Voldemort), is the one that set me off on my recent epic binge on Arctic literature, which is far from over.

Fiennes has made a life of adventuring and exploring, crafting challenging itineraries across some of the most unforgiving terrain on the planet. He solicits sponsorship for the expeditions, and raises funds from book sales and speaking engagements.

This book focuses on his journeys through the world’s coldest regions. Fiennes intermingles historical accounts of exploration and discovery with his own adventures. It is surprising how, in the earth’s most extreme climates, life and travel has not gotten appreciably easier over the last several hundred years.

It was Fiennes’s historical account of the search for the Northwest Passage, represented in the greatest drama by Sir John Franklin’s final expedition, that drove me to seek out other books on the subject – I can recommend The Man Who Ate His BootsFranklin’s Lost Shipand Frozen in Time for starters. His accounts of his own travel in Norway, Greenland and the Canadian Arctic made me want to pack my bags and visit those magnificent places.

Fiennes faces death and disfigurement several times in the course of Cold. His determination and courage are notable but he is definitely a man of an earlier era. There are interviews with Fiennes here and here. A review of Cold can be read here.

You can get a copy of the book here (South Africa), here or here.

A new ocean MOOC starting on Monday!

Online learning with SDI
Online learning

This one snuck up on me. Starting on Monday 25 April (yes, this Monday), a massive open online course (MOOC – remember those?) about science-based solutions to challenges facing the world’s oceans becomes available to the curious. It’s a collaboration between Kiel University in Germany, its GEOMAR Hemholtz Centre for Ocean Research and “cluster of excellence” (I don’t know!) The Future Ocean, and the International Ocean Institute.

The course syllabus is comprehensive and spans 10 weeks of online study. You will cover topics from oceanography, marine biology, and geology. The aspects of the course related to humans include ocean governance, human-ocean interactions, changes happening along our coastline, and – most importantly – solutions from marine spatial planning to ecosystem management.

It looks very comprehensive and unmissable if you’re a marine freak. Go to oceanmooc.org to learn more and sign up. For your own privacy, protection and future access (and this applies to every website that offers you the option, not just this one) don’t sign in with your facebook, linkedin or other credentials.

Get to it.

Article: Outside on acoustic sanctuaries for whales

Departing dolphins, and Christo
Departing dolphins, and Christo

Whales and dolphins make extensive use of sound to communicate. Some of the purposes of this communication may be to organise during a hunt, to socialise or to co-ordinate group movement.

The predominance of long-distance shipping as a cost-effective and efficient way to transport goods around the world has increased the amount of anthropogenic noise in the ocean to the extent that, in some parts of the world, populations of wild cetaceans struggle to make themselves heard in order to communicate with each other.

Outside Online describes a recent paper that proposes “acoustic sanctuaries” to protect cetacean populations of marine mammals off the coast of British Columbia in Canada. This is a fascinating idea, and need not be difficult to implement:

These quiet areas could be pain-free places for governments to formally institute quiet zones, the paper argues. Ships wouldn’t have to be rerouted, the authors note, they would simply have to continue avoiding sensitive areas.

Read the full article here.

To read more about acoustic communication between cetaceans, try this article, the book Listening to Whales by marine mammal scientist Alexandra Morton, or (for a touch of eccentricity) the book Thousand Mile Song.

Article: The Atlantic on finding whales by listening

Humpback whales
Humpback whales

Let’s stay with whales for a bit. I love tales of serendipity in science. My favourite Ed Yong writes for The Atlantic about a team using multiple (160, to be exact) hydrophones (underwater microphones) to listen for fish in the Gulf of Maine. They were able to visualise the locations of millions of herring; they also discovered that they could hear thousands of whale calls clustered in specific locations, mostly humpbacks, which are very vocal animals. But this was not all:

Each whale species calls within a certain frequency range and makes its own distinctive repertoire of sounds. Using this information, the team could look at their recordings and extract the locations of five huge filter-feeding species (the blue, fin, humpback, sei, and minke) and three toothed ones (sperm, pilot, and killer).

The team was able to visualise the spatial distribution of the whales, and scientists may be able to use the multiple-hydrophone technique to study  the interactions of predator and prey species.

Marine-related MOOCs from edX

As a fourth and final (perhaps) installment to our guide to ocean-related MOOCs for the curious armchair scholar, here is a list of offerings from provider edX, including one about SHARKS. All about sharks!

I have only just discovered edX, so (unlike Coursera, Future Learn and Open2Study) I have not done any of these courses, and don’t speak from experience. The format looks similar to Coursera, so you can pay to get a “verified certificate” for the course, or just choose to audit it (like a Scientologist… bad joke, sorry), which doesn’t cost anything. Like Coursera, edX has an app so you can work (on certain mobile-friendly courses) on your iPad or Android tablet.

Sharks! Global Biodiversity, Biology, and Conservation is from Cornell University and the University of Queensland, and looks like a complete primer about sharks, from their evolutionary and life history all the way through to management issues and human-shark interactions. The next sessions starts on 28 June. Will I see you there?

Tropical Coastal Ecosystems (also from the University of Queensland) is self-paced, which means you can start whenever you want to. The Great Barrier Reef is used as a study example in many instances, and the course deals with coral reefs, seagrass meadows, and mangrove swamps.

Two courses that are focused more specifically on climate and related science are:

Climate Change: The Science from the University of British Columbia in Canada doesn’t have any current or future sessions scheduled, but you can still view the course material. This course not only covers climate, science, but aims to equip you to evaluate climate science, and to communicate facts about the climate to others.

Sensing Planet Earth – Water and Ice from Chalmers University of Technology in Sweden deals with the measurement and monitoring of earth’s ice and water bodies, in order better to understand the changing climate.

Have fun!
