How seakeeping analysis reveals surprising differences about ship seaworthiness

Grocery stores are places of scientific discovery. It’s true: biologists wanted to know just what was in a package of store-bought dried mushrooms. Taking an extremely close look, they sequenced the DNA of each mushroom and were stunned at what they found. They were mushrooms all right – but what

What the playground can teach us about resonance in dynamics

Kids are always happy to visit a playground. When my son turned three, the swings became one of his favourites. He always wanted to go higher and higher. At that age, he hadn’t quite figured out how to swing by himself yet, though, and needed a push to keep going.

When wave steepness pinpoints worst case sea states for mooring design (and not wave height)

Vintage wind-up toys may seem simple, but they are mechanical marvels. Many intricate details turn a compressed spring into something like a walking robot. But while these designs are clever, they have their limits. For example, nothing stops them from tumbling off the edge of a table or down the

ProteusDS Oceanographic Release 1.2

ProteusDS Oceanographic v1.2 is now available for download. Read more on highlighted changes for this release below. Estimated component depths Fine-tuning sensor positions on a mooring to reach target instrument depths can be tedious and time-consuming without quick feedback. The estimated depth of components is now available in Designer.

Why you see modular oceanographic mooring design everywhere

Something strange happens to you when you start thinking about buying a new car or bicycle. These are relatively big purchases for most people, so you spend a bit of time thinking about a few choices. When you spend time thinking about different options, the subtle design details and shape

How to correct subsurface mooring knockdown

Manatees are sophisticated, high-performance swimmers. You might look at one of these cuddly blubberous hulks and think otherwise, but it’s true. By high performance, I don’t mean they are incredibly fast. Instead, it’s how they keep their ungainly bulk in control. Because they are so large, it would be a

When to check instrument depth in oceanographic mooring design

In the late 19th century, the Hawaiian sugar industry was sweating, but it wasn’t from the heat. It was because of rats. The rat population was eating up way too much of their sugar crop. And the problem was getting worse. So what could be done to help keep things

Dynamic Systems Analysis Ltd. is an organization that cares about the ocean; it plays the central role in our business. It is a source of beauty and inspiration to our team. Whether we’re surfing, sailing, looking at it, or working on it, we are passionate about the ocean that lies

How mooring deflection disrupts oceanographic data quality

Sloths may be slow, but they’re not stupid. They rely heavily on stealth and blending in with their surroundings. Now, frankly, relieving themselves up high in a tree would make a lot of noise and attract unwanted attention. So how do they handle the call of nature? It is risky,

Why drag force is more than just resistance

It’s tough to beat Nature. You don’t have to look in a top secret lab to find one of the most miraculously slippery fluids on the planet. You can just look at your knee! Lining many of your joints is an egg-white coloured substance called Synovial Fluid. Among its many
