For my #CYO2 on #ArchMethods, I listened to a riveting discussion from @ArchandAnthPod with Chanelle Zaphiropoulos ( @sharksandwrecks), a MA candidate/scuba-enthusiast from the Univ. of Malta ( @UMmalta) /1
Chanelle’s work lies at the intersection of biology/archaeology/ethics--& as global climate change occurs & weather patterns/seabed topography/sea levels rapidly shift, salvage archaeology & collecting/measuring/comparing marine ecology data are more crucial than ever /2
Archaeology + Social Activism:

Coastal archaeological sites under threat from rising sea levels hold vital clues to past land ownership. Chanelle (w/ the help of volunteers) studies/preserves them after natural disasters in Newfoundland, her home (Algonquin Anishnaabeg land)https://abs.twimg.com/emoji/v2/... draggable="false" alt="✊" title="Erhobene Faust" aria-label="Emoji: Erhobene Faust">/3
These disappearing sites serve as phys. evidence of historical ownership in land reclamation court cases, affecting 1000s of indigenous Canadians. Well done, Chanelle.

Ms. “Zap” also collabs w/ the Shipwreck Preservation Soc. of Newfoundland & Labrador. Let’s https://abs.twimg.com/emoji/v2/... draggable="false" alt="👀" title="Augen" aria-label="Emoji: Augen"> @ her methods /4
Context measurements & diverse relationship data--comparing wreckage fields based on location, observing meteorological patterns, listening in on folk/fishermans’ tales--can be used in conjunction w/ mathematical algorithms to predict shipwreck locations! And it has worked! /5
Shipwrecks are pop. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🏠" title="Haus" aria-label="Emoji: Haus">’s 4 sponges/coral/hard shelled invertebrates b/c they provide a durable substrate on which to grow. They also give a definitive terminus post quem for these organisms--a concrete metric by which to measure depth/pressure/temperature Δ’s effect on growth /6
B/c of this, Chanelle views marine ecosystems on historical watercrafts as #majorhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🔑" title="Schlüssel" aria-label="Emoji: Schlüssel"> ‘s in predicting growth patterns of natural reefs

The ways in which nature reclaims human cltre is fascinating--& Chanelle is writing her Master’s thesis on how it transformed the HMS Olympus /7
Studying the HMS Olympus--a N35 Odin-class #WWII #submarine which sank off Malta& #39;s coast in 1942--presents several ethical dilemmas

Firstly, it’s a military grave of 89 men. Secondly, its artifacts+structure are now a living, breathing home to 100s of diff. marine species /8
Chanelle doesn’t think it shld be resurfaced--and I agree.

New advancements in Low Visibility Diving tech like Compressed High-Intensity Radar Pulses (CHIRP) & USBL Positioning Systems make artifacts/wrecks possible to study w/o disturbing or damaging the natural environment. /9
Strong-willed & gritty, Chanelle remarks on her ongoing struggle in a male-dominated diving realm. Although shorter than her peers, a background of ballet & musical theatre (aerobic exercises) allows her to excel in performing cmplx maneuvers w/ hvy. equipment underhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="💧" title="Tröpfchen" aria-label="Emoji: Tröpfchen"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Applaus-Zeichen" aria-label="Emoji: Applaus-Zeichen"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="🙌" title="Raising hands" aria-label="Emoji: Raising hands"> /11

But alas!

Across the Mediterranean, shallow & easy-to-access wrecks have been scavenged for the ultimate “prizes:” rare art+precious metal objects. But here’s the issuehttps://abs.twimg.com/emoji/v2/... draggable="false" alt="⬇️" title="Pfeil nach unten" aria-label="Emoji: Pfeil nach unten">/12

CZ goes through a cmplx desalinization+demoisturizing process w/ every artifact she finds.

Fragile artifacts like glass vessels can burst w/ pressure changes & require expert salvaging. On war wrecks, UXBs can still be live, detonating w/ the slightest movement https://abs.twimg.com/emoji/v2/... draggable="false" alt="😱" title="Vor Angst schreiendes Gesicht" aria-label="Emoji: Vor Angst schreiendes Gesicht"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="💥" title="Symbol für eine Kollision" aria-label="Emoji: Symbol für eine Kollision">/14
Ms. Z’s combination of archaeological inquiry w/ ecological & ethical questions, non-invasive approaches, has led her to emerge as a leading voice in marine archaeology. It’s inspiring to me, as someone who’s interest in the field started by the sea. Here are some pics /15
I’ve scoured the tidal mudflats & riverbeds of New England for signs of the past. I’ve found pocket watches, hotel tokens, coins, military paraphernalia, glass marbles, and over 2k antique bottles (nearly all pre-1900). I always remove trash/debris when I go mudlarking too /16
