When profilers are optimized for control

It’s impossible to see a Frogfish. It’s not because of their camouflage, even though it is incredibly intricate. It’s not because they swim quickly, either: they are not very streamlined, and many Frogfish will lumber around slowly and mainly try to stay in one spot. What I mean is that

When prolifers are specially adapted to ride ocean waves

When you think of Owls, “ninja” might not be the first thing that crosses your mind. But there’s a good argument for it: like a ninja, owls are incredibly stealthy. These birds are the only animal that can fly absolutely silently. Their silent flight ability stems in part from their

Why profilers stop massive data processing headaches

When the going gets tough, I like to think about the year 536, and it helps me feel better. The year 536 was a seriously difficult one: a strange fog enveloped most of Europe and large parts of Asia. The mysterious fog was so thick that daytime sunlight was reduced

When it is sensible to use nonlinear Froude-Krylov forcing

There’s nothing about tanks that makes them look like they’re ready to fly. At the best of times, tanks are squat and stocky, mean-looking machines meant for slowly crawling over the worst terrain the ground has to offer. In World War 2, tanks were a critical element. Getting tanks to

Why parts libraries are essential to save time in mooring design

After a disastrous World War 2 naval battle, a lone allied warship was left surrounded behind enemy lines. Vastly outnumbered and outgunned, the situation seemed very grim. Still, the crew came up with a plan to sneak back home: disguise the warship as an island. The crew gathered as much

When to avoid a static solver in oceanographic moorings

It was when the traffic light turned green, and my car lurched forward from a stop when it happened. A warning light flickered on the dash, but then quickly turned off again. Fortunately for me, it wasn’t a sign of disaster with the engine – it was just a light

How to effectively model oceanographic surface buoy dynamics

Flying sheep may help you get to sleep, but they can save your life, too. In 1934, the Italian army had a huge logistics problem: crossing one of the most inhospitable deserts in the world. Resupply for the trip was vital, and the army had to consider their options carefully.

How to systematically evaluate oceanographic mooring compliance

People that live in northeastern India use tangled foliage to speed their way through the jungle. But it takes a lot of patience. They can do this with certain kinds of plants, like the rubber tree. As you might expect from a rubber tree, the roots are quite flexible as

How to control uncertainty in buoy drag coefficient when designing oceanographic moorings

It was the summer of 1991 and I stood in front of the first hedge maze I’d ever seen before. What could be more fun to a young boy that getting lost in a hedge maze and finding your way out? I had a simple plan: get totally lost as
