Journal Article
Azpiroz-Zabala, M., Cartigny, M. J. B., Sumner, E. J., Clare, M. A., Talling, P. J., Parsons, D. R., & Cooper, C. (2017). A General Model for the Helical Structure of Geophysical Flows in Channel Bends. Geophysical research letters, 44(23), (11,932-11,941). doi:10.1002/2017gl075721. ISSN 0094-8276

Meandering channels formed by geophysical flows (e.g., rivers and seafloor turbidity currents) include the most extensive sediment transport systems on Earth. Previous measurements from rivers show how helical flow at meander bends plays a key role i... Read More

Seasonal expression patterns of clock-associated genes in the blue mussel Mytilus edulis (2017)
Journal Article
Chapman, E. C., O’Dell, A. R., Meligi, N. M., Parsons, D. R., & Rotchell, J. M. (2017). Seasonal expression patterns of clock-associated genes in the blue mussel Mytilus edulis. Chronobiology International, 34(9), 1300-1314. doi:10.1080/07420528.2017.1363224

Environmental cues allow organisms to synchronise their internal biological rhythms with external environmental cycles. These rhythms are regulated on a molecular level by oscillating interactions between clock genes and their proteins. Light is a pa... Read More

Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons (2017)
Journal Article
Azpiroz-Zabala, M., Cartigny, M. J. B., Talling, P. J., Parsons, D. R., Sumner, E. J., Clare, M. A., …Pope, E. L. (2017). Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons. Science Advances, 3(10), (e1700200). doi:10.1126/sciadv.1700200. ISSN 2375-2548

Seabed-hugging flows called turbidity currents are the volumetrically most important process transporting sediment across our planet and form its largest sediment accumulations. We seek to understand the internal structure and behavior of turbidity c... Read More

Nonlinear Modeling and Verification of a Heaving Point Absorber for Wave Energy Conversion (2017)
Journal Article
Gilbert, J., Guo, B., Jin, S., Parsons, D., & Patton, R. (2017). Nonlinear Modeling and Verification of a Heaving Point Absorber for Wave Energy Conversion. IEEE Transactions on Sustainable Energy, 9(1), (453-461). doi:10.1109/tste.2017.2741341. ISSN 1949-3029

Although the heaving Point Absorber (PA) concept is well known in wave energy conversion research, few studies focus on appropriate modelling of non-linear fluid viscous and mechanical friction dynamics. Even though these concepts are known to have n... Read More
