What a rewarding #OSM2024! Carson Witte, Lindsay Hogan, Jerry Liu, and Prof. Zappa were honored to share their latest findings on currents, waves, the air-sea interface, and physical modeling of the momentum, heat and kinetic energy budgets. It was a pleasure connecting with

The Zappa Lab reunion at #OSM24 in New Orleans: celebrating our journey and achievements in ocean sciences. Here's to many more waves of discovery! 🌊🔬🥂 Columbia Climate School Columbia University LDEO

#tbt 🛰️Join us on the #AirToSea expedition aboard R/V Falkor to track Trichodesmium—a climate-regulating organism. Scientists used advanced technology like Uncrewed Aerial Vehicles (UAVs) to explore changing sea surface temperatures and dynamic ocean fronts in real-time! 🌊

#tbt 🌊Ocean study = 🌍climate understanding. Our Columbia University team aboard RV Falkor used UAVs & high-tech instruments to understand ocean changes on various scales using real-time data, which led to a pumice patch discovery. The team also used infrared cameras to study sea surface

🌊Exciting research ahead! Prof. Zappa & Co-PI Kaus Raghukumar visited 🚢RV Sally Ride at Scripps Institution of Oceanography in San Diego last month to meet with the crew. DEES graduate student Lindsay Hogan is in the lab LDEO ⁩gearing up for the upcoming 3-week research cruise off

#tbt In 2012 during the M91 Cruise aboard the R/V Meteor in the coastal upwelling regions off of Peru, visiting The Fulbright Program Scholar Daniel Kiefhaber measured wave slope probability distributions using the Reflective Stereo Slope Gauge (RSSG) that he developed based on the

In the Spring of 2024, we spent 4 weeks in the SUSTAIN Lab University of Miami for the phase-2 testing of a new system of infrared cameras (MultIR), measuring temperature differences & turbulence at multiple depths within the top millimeter (skin) layer of the ocean surface. LDEO

The SUSTAIN (SUrge-STructure-Atmosphere INteraction) Lab University of Miami is a wind-wave tank that can measure air-sea interaction under various wind & wave conditions. This video shows 50-60 m/s wind- and mechanically-generated waves in the SUSTAIN wind-wave tank. Note the spray being

The MultIR system includes 3 infrared cameras with unique spectral ranges that ‘sense’ radiation from different optical depths in the viscous/thermal boundary layers. The surface thermal boundary layer is known as the “skin layer,” which is the top millimeter of the ocean, and is

It was fun to visit the R/V Marcus G. Langseth again while it was docked at the Brooklyn Navy Yard in early July. It had been nearly a decade since we last saw the vessel, which was back in November 2014 when it was docked Woods Hole Oceanographic Institution (WHOI).

#tbt In 2016, R/V Falkor traveled the Timor Sea between Australia and Guam. We observed large surface blooms of cyanobacteria (Trichodesmium sp.), skimmed the sea surface using a remote-controlled catamaran, launched an Uncrewed Aerial System (UAV) from the deck, and witnessed a

On Sept 6 from 11 AM - 1 PM, Prof. Zappa is hosting Prof. Lega from Università degli Studi di Napoli "Parthenope" for the SAfE - Situational Awareness for Environment - See the unseen Science Tour. This event will explore how advanced technologies such as remote sensing and environmental forensics enable us to

📢NEW Zappa Lab publication! Learn about the radiative and geometric properties of melting first-year landfast sea ice in Kotzebue Sound, Alaska, in Prof. Nathan Laxague’s new EGU paper. This work was done while Nathan was a Postdoctoral Research Scientist
