CitSci Jungle Rhythms project finished!

After an amazingly short ~475 days the Jungle Rhythms citizen science project finished !

I hereby would like to thank all citizen scientists who contributed to the project and made it into a success, transcribing ~30K site years of tropical phenology data in no time.

I will now start the post-processing. I will report on this shortly as I make my way through the large dataset consisting of more than 300K classifications and additional remarks collected from the Talk forums. Intermediate results have shown that the data collected are of an outstanding quality, illustrating the swift and accurate work by citizen scientists. I’m confident the complete dataset will be of an equal high quality.

Once more, my thanks and gratitude go out to all volunteers who made this possible !

Robots are -also- after your academic job

Rapid development in machine learning and artificial intelligence has allowed previously complex consumer applications and jobs to be automated at an ever increasing pace. But make no mistake, machine learning will also displace academic jobs with only those remaining which wield the right tools combined with the best and brightest ideas.

Voice assistance allow you to order anything online, translation services process natural language ever better, ordered packages are picked by robots, and soon a drone might deliver them. All these advances in automation are due to recent software and hardware developments which result in job loss.

Yet, in academia the rise of automation and ‘robots’ stirs less of a concern. The general feeling remains that core functions of academic jobs are too complex to be sufficiently automated. This core function is the creation of new hypothesis to be tested. However, a large part of academic work, especially in ecology, still relies on encyclopedic knowledge, collection management and often tedious work. Encyclopedic knowledge and many of these mundane academic tasks can be reduced to harder classification or sorting problems (of samples stored in collections and data sets).

As with the soon to be obsolete Uber driver, harder classification problems,  such as driving a car, become easier to solve using advanced machine learning techniques. One can argue that automation will free up time to do more hypothesis testing, and increases the pace of science. This arrival of machine learning into mainstream research can be seen in a number of recent high profile publications from classifying leaves in paleobotany to mapping poverty.

I argue that in the near future it will be a requirement to wield the tools to implement (large scale) machine learning approaches to remain competitive in most academic fields. With austerity and budget cuts, a failure to do so might lead to some academics being replaced by evermore sophisticated algorithms and not necessarily lead to a shift in their job content. A urgent shift is needed in the skill sets of many scientists, extending past statistics into the fields of computer science and machine learning.

 

Citizen Science restores trust in science; isn’t exploitative

A recent review comment made the claim that Citizen Science (referring to my Jungle Rhythms project) is exploitative. With due diligence on part of researchers, not only is this comment misguided, it also is a testament to a pervasive ivory tower way of thinking about science.

Science is often perceived as a field of the select few with limited interaction between the scientific world and the public. Or as aptly put in the Guardian Science section: “Science is the invisible profession. Most people have no idea what scientists do, and may harbour a vague feeling of suspicion or uneasiness about the whole endeavour.”

This lack of transparency has been abused many times over to create doubt and confusion in order to push a political agenda, fueling among others climate skepticism. In addition, a lack in transparency and limited communications creates a less educated public and one which is less used to dealing with complexity.

Citizen science provides a way to counter all these issues. It allows citizens to actively contribute to science, directly communicate with scientists and at times attain PhD worthy knowledge through self-study. In today’s society with increasing distrust in science through fake news and “alternative” facts this direct and transparent communication about science between scientists or science communicators and the public is key to retain or restore trust in science.

R arctic polar plots

For a project I needed to create an appealing plot of the arctic, showing the location of some field sites. I’ve posted this map on twitter earlier today. Below, I’ll outline a simple routine to recreate this plot, and if need be adjust it to your liking.

First of all I downloaded an appealing background from the Blue Marble dataset as created by NASA. Geotiffs can be downloaded here or by direct download following this link. Alternatively you can download the less realistic and more summary style graphics as produced by Natural Earth.

After downloading the Blue Marble geotiff you trim the data to the lowest latitude you want to plot. Subsequently, I reproject the data to the EPSG 3995 projection (or arctic polar stereographic). All this is done using GDAL. This step could be done using rgdal, but at times this doesn’t play nice. For now I post the command line GDAL code.

UPDATE: the below command line gdal code is not necessary anymore as I call the raster library in R now which works fine in dealing with the reprojection after some fiddling.

The remaining R code ingests this background image and overlays a graticule and some labels. For this I heavily borrowed from the sp map gallery.

COBECORE project accepted for funding

Past September (2016) I wrote the “Congo basin eco-climatological data recovery and valorisation” or COBECORE proposal together with several partners building upon and inspired by the success of the Jungle Rhythms project.

The Jungle Rhythms uses citizen science to transcribe old colonial records of tree phenology (seasonal changes in the state of the tree). The project illustrates nicely that historical data can still hold significant value for current day research, and data which seem out of reach due to the challenging nature of transcription can be tackled with the generous help of citizen scientists.

Given this notion, I expanded upon the basic idea of Jungle Rhythms in order to digitize and transcribe further historical colonial records of eco-climatological importance as stored in the state archives in Brussels. Although the competition was stiff in the thematic axis 3 & 6 (cultural, historical and scientific heritage) of the Belgian Science Policy Office BRAIN call with close to 90 submissions and a rather rough 16% success rate, the project was still selected!

I’m therefor happy to announce the informal start of the COBECORE project as funded by the Belgian Science Policy Office (pending political approval of the science budget).
