Post-processing after small craft recording

Over the last two days, Sydney, Kelsey, Bettie, and I worked on recording the small boat Jamaica Town. Our process ranged from making basic observations, such as how many rows of seat the boat had and its color, to taking detailed measurements of the watercraft. After we collected the data our group worked on another … Read more

Trilateration, Trials, and Tribulations

After a successful day of diving and rectifying the spatial distances between each cannon yesterday, my team was confident that finishing the last of these measurements would go smoothly. While we were working on the first measurement, an un-numbered cannon was discovered. It seemed as if the cannon had been previously found on the free … Read more

 Low Visibility? No Problema!

Today’s diving consisted of low visibility, persistence, and good communication. Visibility varied between <1 foot to 1 ½ feet depending on of the amount of diver activity in an area and the surge. Two teams attempted and completed trilateration measurements between datum points on the cascable and muzzle of each cannon in piles found so … Read more

Photos, photos, and more photos: How to make a 3D model

After a morning of diving, Dr. Richards, Hannah, Devin, Elise, Lauren, and I set out for an afternoon in Puerto Viejo, a town near Cahuita and home to one of our sites, El Lanchon. El Lanchon is the remnants of a 19th century oil barge used for transporting heavy machinery that was abandoned by Loffland … Read more

Day 1: Site Orientation

After a full day of being stuffed into vehicles with little, or no, leg room (oh, the hard life of a tall man), beginning our first day of work in the water felt like a blessing.  After a breakfast of eggs, beans, rice, and fresh fruit (the fruit tastes way better here than stateside), we … Read more

Discovering Cannon – recording what we found

During this morning’s dive, the group was tasked with using proforma to mark, measure, and sketch the cannon we found the previous day. This task was made increasingly difficult because of the large surge underwater and low visibility. Each cannon was measured along the shaft, muzzle, and cascabel. In total, eight cannons have been found … Read more
