Call me Ishmael: Professional Insomnia

All professionals accept that there will be occasions when work gets in the way of sleep and that odd hours me be required to get the job done. Generally this interruption in sleep is temporary and isolated to project deadlines or mission critical tasks, but for scientists aboard research vessels this may be a de […]

Sediment Traps: Historical Trends and the Promise of Inovation

[NB: The first entry in this series was published here, Introduction to Sediment Traps, which covers the motivation, use and issues of sediment traps.] Although validation of the data was lacking, sediment traps (or sedimentation traps as they were once called) were being used by the 1970s in the study of lakes (Davison et al., 1982; […]

Introduction to Sediment Traps

[NB: The second entry in this series was published here, Sediment Traps: Historical Trends and the Promise of Innovation, which covers some of the history and development of sediment traps as well as my own hopes for the field moving forward.] The biological carbon pump (BCP) is the mechanism whereby marine, biological systems sequester atmospheric carbon into […]

Philosophy Monday: On the Origin, Propagation and Cause of Variations

Darwin’s On the Origins of Species provided a vivid and practical mechanism to explain how variations within a species can be selected for. This mechanism became known as natural selection or, perhaps less accurately, survival of the fittest. Although Darwin’s natural selection mechanism was not novel—Malthus described a similar mechanism as actively limiting a population’s […]

Analyzing YSI data through clustering

Update 10/13/15 – Minor improvements to code and an update to the latest findings. CTD data (conductivity, temperature and depth) from a YSI provides a quick and methodologically simple way to estimate the current water column state by, literally, dropping an instrument off the side of a boat. During each deployment the YSI records the […]

Markov Chain Monte Carlo: A Practical Introduction

Markov Chain Monte Carlo simulation sounds, admittedly, like a method better left to professional practitioners and the like; but please don’t let the esoteric name fool you. MCMC, as we like to call is, is a powerful yet deceptively simple technique that can be useful in problems ranging throughout science and engineering. Since this promises […]
