The forces that move the ocean
In the first lecture we asked why the ocean moves. Now we ask how. Like any object, a parcel of seawater obeys Newton’s laws: it keeps doing what it is …
Course: Fundamentals of Ocean Forecasting
Forces Governing Ocean Motion
In the first lecture, we saw why the ocean moves. In this second lecture, Nicholas Hall looks at how – the forces that act on every parcel of water in …
Why the ocean moves
The ocean is one of two thin envelopes of fluid that wrap around our planet – the other being the atmosphere. Neither is very deep compared with the size of …
Introduction to ocean dynamics
This first lecture sets the scene for the whole week. Nicholas Hall introduces the ocean as one of two thin envelopes of fluid – the ocean and the atmosphere – …
Welcome to Week 2: the physics beneath the forecast
Welcome to Week 2. In Week 1, you saw the ocean forecasting system as a whole – the end-to-end chain that turns observations into models, products, and services. This week, …
Ocean forecasting in action, around the world
Throughout this course you have followed the ocean forecasting system as a virtuous loop – from observations, through models and data assimilation, to products, and back again through validation and …
How Ocean Forecasting Supports Services and Decision-Making
This final video of the week brings everything together. Having built up the end-to-end system and the virtuous loop, Stefania Ciliberti now shows the loop at work – in real …
Sustaining the virtuous loop
In the previous activity, you explored the components that make up the end-to-end ocean forecasting system. But these components do not work in a straight line — observation in, product …
The Virtuous Loop in Ocean Forecasting Systems
The last video opened up the end-to-end system and ended on a key idea: users and feedback are essential parts of it. This lecture builds on exactly that – showing …
Inside the end-to-end ocean forecasting system
After exploring the general concepts of ocean forecasting and the historical timeline from ancient mariners to today’s digital opportunities, it is time to understand the main components that make up …
Understanding the End-to-End Ocean Forecasting System
The earlier videos explained why ocean forecasting matters and how it grew. This one opens up the machine itself – the End-to-End Ocean Forecasting System (EEOFS) – and walks through …
From ocean observations to forecasting systems: a brief history
Today’s operational ocean forecasting systems are the result of decades of progress in ocean science, observations, technology, computing, and international collaboration. In this step, we trace a timeline showing how …
From Ocean Observations to Forecasting Systems: A Brief History
Today’s ocean forecasting systems didn’t appear overnight. They are the result of decades – indeed centuries – of progress in ocean science, observation, technology, computing, and international collaboration. In this …
Why do we need ocean forecasting systems?
We have seen what ocean forecasting is and why the ocean matters. Now let’s look at this from a different angle: why do we actually need ocean forecasting systems? What …
Why Do We Need Ocean Forecasting Systems?
The first video introduced what ocean forecasting is. This one asks why we need it – what it makes possible, and what it protects us from. In this lecture, Stefania …
