A Case Study in Maritime Heritage Ecology: Understanding How Structural Changes to the 1898 Shipwreck Portland Affect Biological Diversity and Colonization

open access: yesJournal of Maritime Archaeology, 2023
Shipwrecks are irreplaceable cultural and historical resources, and they also serve as biological habitats. The physical structure of a shipwreck provides habitat for hard-bottom organisms, including sessile invertebrates (anemones, sponges) and ...

Can a 16th Century Shipwreck Be Considered a Mercury Source in the 21st Century?—A Case Study in the Azores Archipelago (Portugal)

open access: yesJournal of Marine Science and Engineering, 2023
During the Spanish colonial era, ships frequently transported mercury across the Atlantic to the New World to be used in gold mining. As many of those eventually sank, shipwrecks may represent a local source of mercury contamination in the marine ...

In the aftermath of Hurricane Irma: Colonization of a 4-year-old shipwreck by native and non-native corals, including a new cryptogenic species for the Caribbean.

open access: yesMarine Pollution Bulletin, 2023
Little is known about early coral settlement on shipwrecks with regard to their species and size compositions. Hurricanes in the Caribbean have a long history of sinking ships but a link with new coral settlement is understudied.

A Quasi-Nondestructive Evaluation Method for Physical-Mechanical Properties of Fragile Archaeological Wood with TMA: A Case Study of an 800-Year-Old Shipwreck

open access: yesForests, 2022
Archaeological wood is a kind of ‘new material’ that has deteriorated due to long-term degradation. The existing wood science theory and evaluation methods are not fully applicable to archaeological wood.

Research on the degradation of ancient Longquan celadons in the Dalian Island shipwreck

open access: yesnpj Materials Degradation, 2022
Eleven celadons with different degrees of degradation excavated from the Dalian Island shipwreck of the Yuan Dynasty (1271–1368 AD) were selected, and the degradation mechanism of the ancient porcelain at marine environment was investigated. The chemical
