Deconstructing Complex Science

COSEE-Ocean Systems offers tools and methodologies, such as concept mapping, that promote effective learning in an ocean science context. Concept mapping is well suited for understanding parts of a complex discipline, such as oceanography. The value of concept mapping lies in both the process of construction and in the final product, the map - a visualization of the journey to understanding.

For scientists, concept mapping helps them share their understanding of connections in the earth system. For educators, concept maps can be powerful tools for exposing and clarifying topics in the classroom. In the North Atlantic Bloom (NAB) webinar series, each presenter made a concept map with attached assets (videos, images, news items, and resources) to use as the basis for their online presentation.

Introduction to the North Atlantic Bloom
Mary Jane Perry | Webinar Archive | Data Set
The NAB Experiment was designed to study one of the major oceanographic events on the planet: the subpolar North Atlantic spring bloom. In her concept map at right, Mary Jane introduces the photosynthetic organisms responsible for the bloom - genetically diverse phytoplankton that produce the food for the rest of the food web, absorb carbon dioxide (CO2) and impact the CO2 budget of the atmosphere - and summarizes the new tools and methods used to collect and measure phytoplankton growth during this experiment.

Physics of the Bloom
Amala Mahadevan | Webinar Archive | Data Set
Phytoplankton need nutrients and sunlight to grow. With the coming of spring, solar insolation increases and the mixed layer shallows, allowing for an increase in phytoplankton growth. In her concept map, Amala Mahadevan explains how modeling has helped researchers to better comprehend the physical dynamics behind what triggers the spring bloom.

How Do You Measure a Bloom?
Eric D'Asaro | Webinar Archive | Data Set
Measuring a bloom poses fundamental challenges because it changes in time as well as space. Here, Eric D'Asaro presents his perspective on how it's possible to measure a moving, changing swatch of ocean at different scales, and the technology needed to collect meaningful data.

Marine Food Web and Carbon Cycling
Nicole Poulton and Ivona Cetinic | Webinar Archive | Data Set
Understanding the change in phytoplankton community composition and the interactions that occur within that community tells us a lot about the efficiency of carbon transfer in the water column. It also provides input for ecological models that are used to predict the impact of climate change on phytoplankton production and circulation. Here, Nicole Poulton and Ivona Cetinic describe the ecological succession that happens during a phytoplankton bloom, and the consequences for the marine food web and export of carbon.

Broader Implications
Craig Lee | Webinar Archive | Data Set
Craig Lee steps back a bit to place the NAB experiment in the context of large-scale climate changes, with a discussion of the physics, biogeochemistry, and biology of the ecosystem. In his concept map, he outlines the big picture: what understanding the dynamics of the spring bloom will mean for scientists concerned about carbon and climate.
