This article briefly outlines underwater cultural heritage
artifact management in Australia from an unregulated
collecting environment in the 1940s – 1960s to the
increasingly regulated environment of the present. In 1993,
in conjunction with new legislation, an amnesty was
declared in order to inventory artifacts collected from now-
protected historic shipwrecks that were in private hands.
The amnesty period concluded with approximately 20,000
artifacts noticed at a time when information was being
stored in a range of formats and to different
standards

This paper presents a novel Underwater Cultural Heritage
(HCH) risk assessment methodology to quantitatively assess
the impact of wave-induced hazards on UCH in coastal
environments at a local level and the screening of UCH sites
at risk. The UCH risk is calculated as a function of
vulnerability (depending on archaeological materials, slope,
and seabed type), hazard (decontextualization, scouring,
and erosive wear), and exposure, computed for the UCH
sites registered in an archaeological database.

This geological analysis aims to determine the origin of
ballast stones recovered from a shipwreck, possibly the Trial,
which sank off the northwest coast of Western Australia in
1622. The analysis involves comparing the characteristics of
the ballast stones with sedimentary rocks from various
locations, particularly in southwestern England, to ascertain
their provenance. The study discusses geological and
isotopic data, including U-Pb geochronology and Sm-Nd
isotope results, to support the hypothesis that the ballast
stones likely originated from the Plymouth area or nearby
regions in southwestern England.

Tin was essential in prehistory for making bronze, and
understanding its origins helps reveal trade networks and
cultural ties. However, many questions about where tin
came from remain. A recent study analyzed tin ingots from
the Uluburun shipwreck, important for Late Bronze Age
trade. It suggested that the tin came from Central Asia and
Anatolia. However, this article argues that the study's
conclusions may not be supported and highlights similarities
with tin ingots from Israel and Britain, suggesting southwest
England or possibly Afghanistan as potential sources.

This study investigates the impact of historic wooden-hulled
shipwrecks on the dispersal of wood-colonizing microbial
biofilms in the deep sea. Two historic shipwrecks in the
northern Gulf of Mexico were studied, using two
experimental microbial recruitment arrays containing pine
and oak samples. The results showed that wood type was
the most significant factor shaping bacterial composition,
but not archaeal or fungal composition, and that proximity
to shipwrecks also had a significant influence on bacterial
and archaeal composition and alpha diversity, but not on
fungal communities.
