Daily Dose: Let there be light

It is often extraordinary what a simple coat of paint, a touch of color, or a simple alteration can make in the appearance of things to see everyday. Even something as simple as cleaning an oil smudge off of the garage door can make the space feel much cleaner and “put-together”, so today will be one of those projects. Our mission? Breath new life into a worn-out looking metal lantern. Our tools? A few “special” coats of paint. Let’s get started. (more…)

Quantifying Error

Being able to appropriately address uncertainty and error is fundamental to the pursuit of science. Without it, results and theory would never match up since theory usually involves a level of abstraction that permits simplification of the problem and observational results are never perfect and include all sorts of uncertainty. Recently I’ve been trying to quantify and approximate the error terms for the data that powers my model. (more…)

Spurious diapycnal mixing in z coordinate models

Introduction Diapycnal mixing is a natural process whereby water parcels of different temperature and/or salinity get mixed.  This process, as opposed to advection, is non-adiabatic (non-reversible) and is governed by diffusive mechanisms. The rate of diapycnal mixing is elevated in coastal waters relative to the open ocean and is responsible for the introduction of nutrients to plankton-containing waters at upwelling zones and within the mixed layer (nutricline/thermocline co-location). Resolution and management of diapycnal mixing was a major issue in all of the early global ocean models. Early work by Bryan (1987) as well as more recent research has found that...

End of the Semester

Believe it or not, but it is already the end of the semester for me and my peers. Somehow nearly four months have disappeared once again into that historical accident that we call the past. Since each of my three classes have required a project to be done for the final, I figure that I may as well adapt each of them here so I can share them with others. For the first entry, here is my Marine Primary Productivity final which includes aspects of both the presentation as well as the paper. (more…)

Climate Change

When I moved to Florida from Boston, I knew there were be a few cultural differences that I would have to work around. That goes without saying, and one of these differences surrounds the whole issue of climate change and anthropogenic carbon emissions. While I like to think that most people are pretty open minded when it comes to scientific consensus[1], my hopes fall a bit short when I look around at Tallahassee. (more…)

Measuring a dye patch from a drone

While my interests are, admittedly, quite broad, I’ve always been fascinated with signal processing and remote sensing. Just imagine the technological marvel that we can accurately measure the amount of chlorophyll, a grove of marijuana or the amount of snow from a satellite whose travelling 1,000s of miles per hour around our planet. If that’s not magic then I don’t know what is! So given this interest of mine, it’s no surprise that I’ve really gotten into the latest developing in a tracer-release study I’m involved in. (more…)
