Overview

This course introduces the concept, development, applications and evaluation of metadata. Through a combination of practical exercises, participants will critically examine metadata issues, standards, and best practices, and will evaluate the role of metadata in Ocean data management.

Objectives
•To introduce Marine Data Managers to the concept of metadata
•To introduce metadata standards used to describe marine data
•To highlight the importance of metadata for your organization
•To provide practical experience in writing good metadata.

Learning Outcomes
•Understand the principles, concepts and types of metadata;
•Explore various metadata standards;
•Understand different issues in the applications of metadata standards
•Gain experience in applying selected metadata standards to the creation of metadata records;
•Practical experience in use of an open source catalogue application to manage metadata;
•Implement metadata decisions in ocean data projects

Abstract

While the sinking formation of Antarctic Bottom Water (AABW) is well understood, how this bottom water "returns home" through upwelling within ocean basins, particularly the Indo-Pacific, remains shrouded in uncertainty. In the 1960s, Munk’s classic "Abyssal Recipes" theory sought to explain these abyssal flows, yet later observations exposed two significant conflicts with real-world data. In 2016, Ferrari, McDougall, and colleagues proposed the "Towards a New Abyssal Recipe" framework, introducing bottom boundary layer (BBL) upwelling to address Munk’s inconsistencies. Drawing on recent evidence of a potential cooling trend in the deep ocean, this talk revisits these debates, offering a fresh interpretation of Munk’s discrepancies and proposing a new mechanism for abyssal upwelling in the Indo-Pacific. It contributes to the ongoing quest to unravel how bottom waters complete their global journey.
