Diversity and gender equity in Southern Ocean ecosystem research: where to from here?

Gender equity and the lack of diversity, particularly at senior levels, are issues of ongoing concern across the sciences. This has implications for the manner in which science is translated into decision making, as it is commonly the more senior levels of scientific research and leadership who have the greatest opportunity to influence policy through science, in large part because scientists at senior levels have greater credibility and standing. However, there is now substantial evidence that diversity in research teams and science leadership can deliver better scientific outcomes and novel solutions. The challenge is particularly acute for polar sciences, which has traditionally been very male dominated. This had led to a wave of recent initiatives to support women in polar science, to highlight role models who do have influence at senior levels, and to promote diversity in Antarctic and Arctic research generally.

This workshop aims to discuss progressing gender equity in science in order to stimulate wider discussion of how the Southern Ocean research and policy communities can better support gender equity and diversity into the future.

Thursday Lunchtime 2

MEASO – Coastal ecosystems – vulnerability to climate change meta-analysis meeting

Facilitators: Jonny Stark and Ben Raymond

Antarctic coastal ecosystems are at the interface between the ocean and the ice sheet and as such face the potential effects of climate change in both realms.

The aim of this project is to examine (and compile observations) what is known about observed change in coastal ecosystems, and combine this with available predictions for change to produce a spatial analysis to identify those areas which may be vulnerable to multiple overlapping environmental changes, as well as those areas that maybe more resilient to change.

 

Thursday 12:45 – Room to be announced

Grab some lunch and come and eat it while we run through the agenda below.

We will try to keep the meeting fairly short, 40 mins or so?

Aims

·         to get a first cut idea of what info exists,

·         identify what needs doing initially, and

·         who is volunteering to do it

 

Other considerations

Scope

Structure

Collaboration platform: Google docs, SOKI?

·         Email list

·         Reference list

·         Data list

 

We will run through the 20 or so general areas and get a quick summary of who/what for each.

1.       Coastal ecosystem features and definition

b.      Changes to primary production

 

Tuesday Lunchtime

R for Antarctic and Southern Ocean science

This will be an informal session, intended as a forum for discussing the use of R in Southern Ocean/Antarctic ecosystem modelling and related work. There will be particular emphasis on some of the tools being developed and used in the Hobart R/Antarctic community, but the discussion will not be limited to these. We will aim to cover:

•             an overview of the recently-begun SCAR/rOpenSci initiative, which aims to strengthen the community of Antarctic R users and the tools that we have available

•             state of the art in R, giving key examples of data access, data manipulation, geo-spatial analyses, and visualization

•             tidyverse packages (especially dplyr, purrr and the upcoming ggplot::geom_sf)

•             mapview, mapedit, plotly for mapping and general visualisation

•             sf, raster, and fasterize packages for dealing with geospatial data

•             in-development packages that deal with mesh-based topological structures for analyses and compelling 3D visualisations (silicate, anglr with rgl)

•             an overview of the AAD/ACE environmental data collection and associated R tools

•             bowerbird maintains a locally-stored, up-to-date data collection of external products such as remote sensing, spatial, and environmental data layers

•             the raadtools package allows this sort of remote sensing and similar data to be read and manipulated in a consistent and simple way

•             the existing setup is accessible to AAD and ACE users, but we will discuss scope for using bowerbird and raadtools yourself, outside of this existing setup

•             various other tidbits: antanym, orsifronts, CCAMLRGIS, croc - packages emerging from local hard-learned habits

•             towards a family of R packages for mapping, processing and visualizing Southern Ocean data
