Description 
Summary

This dataset contains data regarding how branching cold-water corals (Lophelia pertusa) modify flow velocity. The data is recorded in two ways; through Particle Imaging Velocimetry (PIV) on Lophelia pertusa nubbins, and through modelled simulations of how growing L. pertusa will impact resultant flow around them. For modelling, a Smoothed Particle Hydrodynamics (SPH) model was created to simulate coral growth with simple rules, that coral would 'grow' where flow velocity was optimal for feeding. Coral colonies for experimental PIV analysis in flumes were collected 107 metres from the Central Tisler reef in 2014. Flow patterns in the areas behind L. pertusa colonies and around coral nubbins were studied at average free stream velocities using PIV to match a variety of field ranges. A fully Lagrangian numerical SPH approach was employed to model and capture the dynamic and complex hydrodynamic fluid-solid interactions of coral growth. The generation of these data were funded by NERC grants NE/K009028/1, NE/K009028/2, NE/L002558/1, NE/H010025, European Commission ASSEMBLE project (Grant Agreement No. 227799), Royal Society of Edinburgh 48701/1, FORMAS Grant No. 215-2012-1134, EU Horizon 2020 research and innovation program Grant agreement No. 678760 and No. 818123, and UKRI GCRF One Ocean Hub NE/S008950/1. All data have been received by BODC as raw files.
