Always a humbling experience.

Reactive Reefs Exhibition @ The World Parks Congress, Sydney!

Reactive Reefs @ The World Parks CongressPresenting Reactive Reefs at the Oceans + Pavilion at the IUCN World Parks Congress in Sydney

 

Thanks to a generous grant from Barbara Hibino and Carl Page at the Anthropocene Institute, I was able to share the Reactive Reefs exhibition at the decadal IUCN World Parks Congress in Sydney Australia last week.

I was invited to share a portable version of the Reactive Reefs exhibit at the Oceans+ Pavilion as well as participate in a plenary with Dr. Sylvia Earle (can you believe it!) and Dan Laffoley titled "The Future is Cool."

With my colleagues Erica Parke and Blanche D'Anastasi, we presented another talk at the Oceans+ Pavilion titled "Stromatolites, Quadcopters and Sea Snakes." We discussed some of the latest results from our joint collaboration to map the stromatolites of Hamelin Pool, Western Australia and, among other things, what a physicist, biologist and geologist all have in common!

It was truly a phenomenal experience to be surrounded by caretakers of planet Earth and learn about their tremendous efforts and contributions to the worlds most precious resources.

My astrophotography images were featured on the front page of Stanford's website as part of a piece titled "Imagining the universe." Click on the image below to see the feature live on their website! Thank you Robin Wander for the wonderful feature. I am looking forward to the year-long series of speakers, exhibitions and events discussed in the article!

Reactive Reefs 3D Coral Diorama Prototype!

November 14, 2014  •  Leave a Comment

As part of the Reactive Reefs project, we aim to transport the public to coastal reefs systems and inspire protection and conservation efforts for these rainforests of the sea. Using my Fluid Lensing technique, we are able to create 3D images of reefs systems we fly over at cm-scale and higher resolutions. You can see the fluid lensing overview used to create the map in the second video below.

Below you can see an overview of the interactive 3D Coral Diorama. Also, you can read more about how we made this diorama in the paper below by my summer interns at NASA Ames, Charlene Cuellar and Megan Prakash. We look forward to sharing the next three dioramas we are putting together soon! If you would like to see this firsthand, come by the NASA booth at AGU in SF Dec. 14-19.

Announcing Stromatolite Mapping Mission + Field Updates!

APRIL 2014 - Announcing Stromatolite Mapping Mission + Australia Field Updates!

Mapping mission testHamelin Pool, Shark Bay

This was hard to keep a secret, so many already know, but I am thrilled to share the news of an exciting collaboration with Dr. Pamela Reid's group from the University of Miami to map Stromatolites, in Hamelin Pool, Shark Bay, Western Australia, home to Earth's oldest reefs and organisms, for another high-resolution underwater mapping effort for the Reactive Reefs project. I am in the field from mid-March until the end of April mapping Stromatolites around Shark Bay (photo below by Ergin Karaca).

The hypersaline waters here have kept this microbial community thriving and also helps to keep the massive sharks at bay, though the venomous sea snakes love it! The sub-cm resolution 3D maps I will generate are of great interest to research teams around the world and, in particular, to NASA's astrobiology researchers as Stromatolites are Earth's oldest lifeform as evidenced by fossil records dating back to 3.5 billion years ago! All that O2 you love, thank your Stromatolite friends for oxygenating our atmosphere.

Octocopter being tested and prepared for mapping missions (below). This guy decided to put me through the gamut of electrical woes. ESCs mysteriously shorting out, calibrations becoming inaccurate after a few flights, and gains changing with even the slightest change in payload configuration!

Fortunately, after lots of soldering and reassembly, I was able to get this thing stabilized and flying:)
