©2020 Biological and Chemical Oceanography Data Management Office.In the northern Gulf of Mexico seasonal water column stratification may impact how sedimentary biogenic silica (bSi) is processed and preserved by limiting oxygen injections into the benthos, seasonally driving bSi burial efficiency. Hurricane Ida moved through the Mississippi Delta and adjacent Louisiana shelf at the end of August 2021. Thirteen days prior to Hurricane Ida’s landfall in Port Fourchon, LA we collected sediment cores at 3 sites in the topset delta sediment between the Southwest P...
Show moreThis dataset provides information on silica cycling in coastal sediments from the Louisiana shelf region after an extreme storm event. When Hurricane Ida made landfall on August 29th, 2021, this Category 4 storm disrupted sediments of the proximal coastal zone and possibly altered redox and diagenetic conditions. As part of a multi-proxy approach, this data can help inform how an extreme event altered biogenic silica burial over the 10 to 12 months following the storm. Sampling for initial conditions occurred 13 days prior to the storm event from topset delta sediment. Data from this companion project can be viewed here: https://www.bco-dmo.org/dataset/945927.
