Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

The Precipitation Imaging Package: Assessment of Microphysical and Bulk Characteristics of Snow

Atmosphere, 2020
Remote-sensing observations are needed to estimate the regional and global impacts of snow. However, to retrieve accurate estimates of snow mass and rate, these observations require augmentation through additional information and assumptions about ...

The contributions of snow, fog, and dry deposition to the summer flux of anions and cations at Summit, Greenland [PDF]

, 1995
Experiments were performed during the period May–July of 1993 at Summit, Greenland. Aerosol mass size distributions as well as daily average concentrations of several anionic and cationic species were measured.

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Fluorescently Labeled Gradient Hydrogels Reveal Matrix‐Dependent Cell Responses to Substrate Stiffness

Small, EarlyView.
This work demonstrates a new thermophoretic strategy to fabricate fluorescently labeled stiffness gradient hydrogels, enabling contactless stiffness characterization. Fibroblasts cultured on gradient GelMA and Gellan gum hydrogels revealed distinct cell morphology and migration behavior.
