Salt-marsh foraminiferal distributions from mainland northern Georgia, USA: an assessment of their viability for sea-level studies (2020)
Journal Article
Chen, H., Shaw, T., Wang, J., Engelhart, S., Nikitina, D., Pilarczyk, J., Walker, J., Garcia-Artola, A., & Horton, B. (2020). Salt-marsh foraminiferal distributions from mainland northern Georgia, USA: an assessment of their viability for sea-level studies. Open Quaternary, 6(1), 1-19. https://doi.org/10.5334/oq.80

We investigated foraminiferal distributions from two salt-marsh sites at Thunderbolt and Georgetown, in mainland northern Georgia, U.S. Atlantic coast. We analyzed modern epifaunal foraminiferal assemblages across multiple transects consisting of 54...

Organic Pollutants, Heavy Metals and Toxicity in Oil Spill impacted Salt Marsh Sediment Cores, Staten Island, New York City, USA (2020)
Journal Article
Vane, C., Kim, A., Moss-Hayes, V., Turner, G., Mills, K., Chenery, S., Barlow, T., Kemp, A., Engelhart, S., Hill, T., Horton, B., & Brain, M. (2020). Organic Pollutants, Heavy Metals and Toxicity in Oil Spill impacted Salt Marsh Sediment Cores, Staten Island, New York City, USA. Marine Pollution Bulletin, 151, Article 110721. https://doi.org/10.1016/j.marpolbul.2019.110721

Sediment cores from Staten Island's salt marsh contain multiple historical oil spill events that impact ecological health. Microtox solid phase bioassay indicated moderate to high toxicity. Multiple spikes of TPH (6524 to 9586 mg/kg) and Σ16 PAH (15....

Identifying the Greatest Earthquakes of the Past 2000 Years at the Nehalem River Estuary, Northern Oregon Coast, USA (2020)
Journal Article
Nelson, A., Hawkes, A., Sawai, Y., Engelhart, S., Witter, R., Grant-Walter, W., Bradley, L.-A., Dura, T., Cahill, N., & Horton, B. (2020). Identifying the Greatest Earthquakes of the Past 2000 Years at the Nehalem River Estuary, Northern Oregon Coast, USA. Open Quaternary, 6(2), 1-30. https://doi.org/10.5334/oq.70

We infer a history of three great megathrust earthquakes during the past 2000 years at the Nehalem River estuary based on the lateral extent of sharp (≤3 mm) peat-mud stratigraphic contacts in cores and outcrops, coseismic subsidence as interpreted f...

Inception of a global atlas of sea levels since the Last Glacial Maximum (2019)
Journal Article
Khan, N. S., Horton, B. P., Engelhart, S., Rovere, A., Vacchi, M., Ashe, E. L., Törnqvist, T. E., Dutton, A., Hijma, M. P., & Shennan, I. (2019). Inception of a global atlas of sea levels since the Last Glacial Maximum. Quaternary Science Reviews, 220, 359-371. https://doi.org/10.1016/j.quascirev.2019.07.016

Determining the rates, mechanisms, and geographic variability of relative sea-level (RSL) change following the Last Glacial Maximum (LGM) provides insight into the sensitivity of ice sheets to climate change, the response of the solid Earth and gravi...

Testing the Utility of Geochemical Proxies to Reconstruct Holocene Coastal Environments and Relative Sea Level: A Case Study from Hungry Bay, Bermuda (2019)
Journal Article
Kemp, A. C., Vane, C. H., Khan, N. S., Ellison, J. C., Engelhart, S. E., Horton, B. P., Nikitina, D., Smith, S. R., Rodrigues, L. J., & Moyer, R. P. (2019). Testing the Utility of Geochemical Proxies to Reconstruct Holocene Coastal Environments and Relative Sea Level: A Case Study from Hungry Bay, Bermuda. Open Quaternary, 5, 1-18. https://doi.org/10.5334/oq.49

On low-lying, tropical and sub-tropical coastlines freshwater marshes may be replaced by salt-tolerant mangroves in response to relative sea-level rise. Pollen analysis of radiocarbon-dated sediment cores showed that such a change occurred in Hungry...

Exploring mechanisms of compaction in salt-marsh sediments using Common Era relative sea-level reconstructions (2017)
Journal Article
Brain, M., Kemp, A., Hawkes, A., Engelhart, S., Vane, C., Cahill, N., …Horton, B. (2017). Exploring mechanisms of compaction in salt-marsh sediments using Common Era relative sea-level reconstructions. Quaternary Science Reviews, 167, 96-111. https://doi.org/10.1016/j.quascirev.2017.04.027

Salt-marsh sediments provide precise and near-continuous reconstructions of Common Era relative sea level (RSL). However, organic and low-density salt-marsh sediments are prone to compaction processes that cause post-depositional distortion of the st...
