A graph with 3 plots showing the 2015-2024 bottom pressure timeseries at Axial Seamount, the rate of inflation, and the daily earthquake count.

Will Axial Seamount Erupt Again Soon?

A new example Python notebook activity As you may have heard, the seafloor at the Axial Seamount volcano continues to uplift, and is about to pass the level it reached during the last eruption in 2015. In addition, earthquake activity…

Pioneer MAB Profiler – New Python Notebook Activity

A new example Python notebook activity Have you ever wanted to play with profiler data from the NSF OOI? For simple exploration, the OOI Data Explorer is a great way to browse and quickly plot profiler data.  (There are currently…
A graph showing a timeseries of winds (top) and waves (bottom) from the Pioneer MAB Central Surface Mooring in April 2024, showing the passage of a storm which is clearly visible as a peak in both datasets on April 12.

Pioneer MAB Storm – New Python Notebook Activity

A new example Python notebook activity As part of the OOI Data Labs 2.0 project, one of our key goals is to create a new series of Python notebook-based lab activities to help professors and undergraduate students use NSF OOI data, especially…

A workaround for a common error on NDBC DODS

I've long touted the advantages of using NDBC data for introducing students to programming and data analysis, with an oceanographically focused dataset. In particular, their DODS Server makes it fairly easy to access decades of data from hundreds…
2 years of temperature and salinity data from 30m at Irminger Sea Flanking Mooring B showing the annual cycle.

My ooilab Python Toolbox

Data portals are great for navigating and finding useful datasets. But sometimes, the easiest way to access data is with a bit of code, especially when you want to make your own graphs or do a bit of custom processing (like the above example). For…

Introduction to Python – Argo Float Data

This summer, as part of our virtual REU workshop, we introduced students to the basics of using Python to analyze oceanographic data. When we frantically designed the course back in May (during the early even more frantic days of the pandemic),…

Introduction to Python – Data Analysis

Weather is something we all experience. Which is why you'll often find weather-related data used in data analysis courses. Of course, as oceanographers, weather data is far more relevant to our research goals, but it's also useful to start with…

How to Share and Run Python Notebooks

Python notebooks are a wonderful tool for sharing and collaborating on code. Built on the open-source backbone of the Python programming language, JupyterLab notebooks (their formal name) allow you to include code, text, formulas and images…

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 few…

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,…
