NeMO-Net is a single player iPad game where players help NASA classify coral reefs by painting 3D and 2D images of coral. Players can rate the classifications of other players and level up in the food chain as they explore and classify coral reefs and other shallow marine environments and creatures from locations all over the world!

The 7th International Coralline Algae Meeting will take place in Umeå in Sweden this August 2023! The meeting will be followed by an Arctic field trip in Tromsø, Norway.
The meeting will have a multi-disciplinary flavour, welcoming submissions spanning the ecology, biogeochemistry, geology, evolution, physiology and conservation of free-living, crustose and geniculate coralline algae, with a forward-looking view to emerging frontiers in the field.
7th International Coralline Algae Meeting 2023
The full details of registration can be found at the official conference website. Its been a long wait following lockdown!!
Our band The Confusion Dilemma released our first song as part of the Girls Rock London Compilation album released in February. What better way to celebrate World Ocean Day than through song!
Sediment dynamics information provide vital insights into the important role of oceanographic forcing factors on habitat distribution; yet remains an under-utilized physical surrogate in marine habitat mapping studies. An integrated oceanographic and geophysical analyses of dynamic processes combining sediment mobility indices, obtained from coupled-hydrodynamic- wave sediment transport models; with seabed classification has been made at Galway Bay, Ireland.
Maerl or rhodolith coralline red algae beds are abundant in Galway Bay and these beds represent more than 65% – 70% of the maerl habitats in Ireland (De Grave and Whitaker, 1999). Maerl beds are particularly affected by hydrodynamics and increased storminess resulting in recurrent disturbance of the benthic habitat patch during winter storms. Live maerl beds are biodiversity rich coastal habitats and form subtidal and intertidal banks and open marine beds. Dead maerl beds of the branched maerl morphotype are considered to be biogenic sediment with form dense biogenic gravel debris beaches.
Sediment mobility modelling is of importance to a range of disciplines including sediment dynamics, marine conservation, coastal engineering, and renewable energy (Harris and Coleman, 1998; Idier et al., 2010; Li et al., 2015, Joshi et al, 2017a, Coughlan et al. 2021). It is based on the fundamental quantity of bed shear stress and the impact of pure currents, wave-only, wave-induced currents or combined wave-current flow on surficial sediments.
Multibeam backscatter from the INFOMAR national seabed mapping program of Ireland have been utilized for seabed classification using the new machine learning and deep learning libraries in ArcGIS Pro and Python.
An integrated interpretation of the dynamic processes happening at the seafloor is made as a result of the combined wave-current induced disturbance regime during storm conditions. Implications for future conservation management of maerl beds impacted by increased storminess and anthropogenic activity are discussed.

Growing up listening to the sounds of the sea in a shell. The entire seascape captured within the delicate structure of the conch. The inspiration of nature drove me to continuously spend my head in the books when away from the ocean. We didn’t say studying- we said wonder. Wonder about the abyss, the deep blue ocean and its rich inhabitants. How they breathe, how they respire. Eating their way across the food web. A pioneering life history strategy they said- that was our vision. As a student of marine science, there was so much to learn- so much to inspire, digest and reflect upon. The continuous inspiration of the oceans drove me forward into the deep blue wilderness of the abyss. Where had I come from to do oceanography? From a place in my imagination so intrinsically connected with nature. A place unexplored where explorers seek to find wonder. Confronted with scientific understanding I looked to nature to find my muse. Paper after paper, searching for the vision of the natural world within my data. I learned to be a scientist, an ecologist mapping the shallows as well as the deep. Listening to the sea and all its glory I sat there wondering what could be done to save our oceans.
