[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…

## Quick introduction to EOF/PCA analysis

In the field of oceanography, statistical analysis of complex data is a fundamental skill that often calls for mathematics beyond the training of the student. Here I would like to walk through some simple linear algebra and connect it to a well-used yet poorly understood statistical analysis technique. Eigenpairs Given a linear transformation (e.g. ),…

## 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…
