A visit to the Blue Planet aquarium in Copenhagen

On our last day in Denmark, after a week-long family visit between Christmas 2015 and new year 2016, we went to Den Blå Planet, Denmark’s national aquarium. (Actually we were wrong about it being our last day in Denmark, but that’s another story involving Turkish Airlines, who seem to innovate in the field of disappointment.) The aquarium is situated … Continue reading A visit to the Blue Planet aquarium in Copenhagen

A Day on the Bay: Freedom Swim 2016

A day early in April was the date for the annual Freedom Swim, a 7.5 kilometre open ocean cold water swim from Murray’s Bay harbour on Robben Island to Big Bay near Blouberg. As we have in several previous years, we provided boat support for a swimmer. This entails providing a straight course for the … Continue reading A Day on the Bay: Freedom Swim 2016

Bookshelf: Cold

Cold – Ranulph Fiennes 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 … Continue reading Bookshelf: Cold

Hi divers We ventured out to Long Beach last weekend and found the conditions to be less than ideal: surgy, especially for a 10 year old student, and with 3-4 m visibility. Winter diving is around the corner and we look forward to improved conditions. The forecast for the weekend is not that great. The … Continue reading Newsletter: Whether the weather

How to help marine wildlife in distress

  It’s not uncommon to come across marine wildlife – seabirds, seals, turtles – apparently in distress. This is not always the case, so before you mount a complex and dangerous rescue mission, or try to provide help where none is needed, it may be wise to get an expert on the telephone to help you determine … Continue reading How to help marine wildlife in distress

Be a marine citizen scientist (slash conservationist) in Cape Town

Here are a few ways for Capetonians to save the ocean. Some through direct action, and others through support for scientific research that enables policy makers and conservationists to make good decisions about which species and habitats need protection. I’ll update this list as new projects are brought to my attention. If you know of … Continue reading Be a marine citizen scientist (slash conservationist) in Cape Town

A humpback whale on the beach

Last year the carcass of a smallish – about 8 metre long – humpback whale (Megaptera novaeangliae) washed up on one of the less-frequented beaches around the Cape Peninsula. I am very belatedly sharing some pictures of it, not least because one doesn’t often get an opportunity to examine an animal like this up close. I view these … Continue reading A humpback whale on the beach

Article: Outside on acoustic sanctuaries for whales

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 … Continue reading Article: Outside on acoustic sanctuaries for whales
