Poster Presentations

There are many ways to communicate your science to an audience. Lectures, whether part of a conference or symposium, or a lone invited presentation are popular, but represent a linear and one-way form of communication. Slides and information are presented by the speaker to the audience, and there is no time to dwell on a single slide or piece of information before the speaker moves on. Interaction between the audience and the speaker occurs as a question and answer session at the end, if time permits. It is extremely important for the speaker to hone their message so that the audience remembers the content later.

The scientific paper or report is another type of one-way communication that can pack in more information. The reader can take as much time as they like reading and rereading the information. However, the author is not there to interact with the reader and answer questions.

Posters can be some of the most interesting and interactive ways to communicate science to various audiences. It is a two-way form of communication that integrates elements of both the scientific talk and the scientific paper. A good poster promotes dialogue between the presenter and the audience, which is contantly changing as people drift in and out of the conversation. A good poster should rely on graphics to tell a story. If people have to spend too much time reading your poster, then it is not well-designed.

5.25 Trillion Pieces

Data are the currency of scientists, but it is always a challenge to present data in ways that allow their stories to emerge. When you find a data visualization that really makes the story come alive, it can be exciting, both as a researcher and as a teacher. An ecologist for the Wildlife Conservation Society, who himself is quite good at allowing data to tell stories, posted a link on Twitter to this visualization of ocean plastics:

It tells the story of 5.25 trillion pieces of plastic that currently inhabit the oceans. It’s worth a look. The data come from some work by Eriksen et al. 2014 that can be found here:

I haven’t had a chance to read it yet, but will post something about it when I get a chance.
