Data graph showing NDBC Station 44025 air/sea temps and wind speed

Introduction to Python – Part 2

Teaching students how to visualize ocean data is a challenge. But before you get into cognitive theory, choosing colors, or the the principles of (good) visualization design, you really just need to get your students' feet wet plotting some…

Introduction to Python – Part 1

We now live in an ocean of data. And of course, that is literally true for those of us who study the ocean. We've come a long way from the early days of oceanography, when scientists like Nansen, Ekman, and Bjerknes might collect a…

Data Labs Tutorial at WHOI

Today I had the opportunity to virtually present an introduction to the Ocean Data Labs project, along with a short tutorial on working with OOI Profiler data to the WHOI Ocean Informatics Working Group. We had over 40 participants attend, including…

Identifying Dataset Sample Rates

Today's example is rather simple, but it answers a common question I've heard... What is the sample rate of my dataset? For many ocean observatory datasets, the rates are usually pretty well defined and constant in time. For example,…

Merging Datasets For the Win (and export)

If you find yourself with multiple datasets that you need to analyze or plot together, you will probably need to merge them. A merged dataset is handy because all of the data points line up with the same index or timestamp, which allows…

Data requests the easy way with the OOI API

Welcome back to Python Tuesday! The OOI dataset is not exactly the easiest dataset to work with. But a significant reason for this is that the dataset contains over a thousand individual instruments in the system and 36 different instrument…

Seasonal Cycle and Anomaly at NDBC 44025

The Mid Atlantic has one of the largest summer to winter changes of sea surface temperature in the world. But you don't have to take my word for this, we can use real data to see how large the change is! In last week's example notebook,…

Modeling Seasonal Data

Welcome to Python P-Tuesday! In this new series of posts, I hope to bring you a number of Python examples that can help you and your students learn some of the ins-and-outs of using Python for Oceanographic data analysis, especially when…
