Check out the thread below for a new ocean colour NPP data product developed by us.

[Dr Tommy Ryan-Keogh @tjryankeogh]

@esa @PlymouthMarine For access to the data you can check out the @SOCCO_Science Zenodo repository where we will be applying regular updates going forward to this data product

[Dr Tommy Ryan-Keogh @tjryankeogh]

@esa @PlymouthMarine By proving multiple algorithms we hope that users can interrogate the distribution of NPP to identify consensus or outliers for informed decisions of regional analyses

[Dr Tommy Ryan-Keogh @tjryankeogh]

Here we took 5 different algorithms and applied them to the @esa @PlymouthMarine Ocean Colour Climate Change Initiative data to develop one of the longest records available for NPP

[Dr Tommy Ryan-Keogh @tjryankeogh]

Very pleased to announce that our new data product paper on global oceanic multi-model net primary productivity is out now in @ESSD_journal

Not sure if anyone still uses Twitter these days(!), but I want to get the word out that I will soon be hiring 2 postdocs (and recruiting PhD students) to join me at the University of St Andrews in Scotland. All things ocean, carbon, and climate. (1/2)

[Dr Martin Moloto (PhD) @MartinMoloto]

Proud to share my first author and first publication from my Ph.D co-authored by @SandyThomalla @oceanchiq et al. Here, we use historical datasets and satellite match-ups to develop a remote sensing algorithm for detection of multiple phytoplankton groups in the Benguela.

[Sandy Thomalla @SandyThomalla]

@MartinMoloto @oceanchiq So freaking proud of this paper and of you!

[SOCCO @SOCCO_Science]

@esa @PlymouthMarine @SandyThomalla The authors @SandyThomalla @Phytoplankton @tjryankeogh & @oceanchiq would like to thank all the institutions and funding bodies which made this research possible @CSIR @dsigovza @NRF_News @MARIS_UCT

[SOCCO @SOCCO_Science]

@esa @PlymouthMarine @SandyThomalla We may have found one of the reasons why larger marine species such as whales, seabirds and seals have begun to alter their breeding and feeding patterns across the Southern Ocean

[SOCCO @SOCCO_Science]

@esa @PlymouthMarine @SandyThomalla Seasonal adjustments such as this also raise concerns that the base of the food web may become desynchronised from higher tropic levels, known as the match/mis-match hypothesis.

[SOCCO @SOCCO_Science]

@esa @PlymouthMarine @SandyThomalla The seasonal adjustments we find are being driven by large scale changes in ocean physics and chemistry, which could impact global climate by altering natural CO2 uptake
