Satellite Doppler Observations for the Motions of the Oceans [PDF]
Bulletin of the American Meteorological Society, 2019 not required. (Capsule Summary) Workshop on Doppler Oceanography from Space. What: This workshop brought together oceanographers and radar experts to discuss how new radar technology can be used in existing and future satellite missions to directly measure the motions at the ocean surface, namely currents and waves, and their relation to ocean vector ...

MPC-Based Collaborative Control of Sail and Rudder for Unmanned Sailboat
Journal of Marine Science and Engineering, 2023 In the traditional motion control method of an unmanned sailboat, the sail and rudder are divided into two independent controllers. The sail is used to obtain the thrust and the rudder is used to adjust the yaw angle.

Sustaining observations in the polar oceans [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Abstract Polar oceans present a unique set of challenges to sustained observations. Sea ice cover restricts navigation for ships and autonomous measurement platforms alike, and icebergs present a hazard to instruments deployed in the upper ocean and in shelf seas.

A Plankton Detection Method Based on Neural Networks and Digital Holographic Imaging
Chemosensors, 2022 Detecting marine plankton by means of digital holographic microscopy (DHM) has been successfully deployed in recent decades; however, in most previous studies, the identification of the position, shape, and size of plankton has been neglected, which may ...

Observations of Rogue Seas in the Southern Ocean [PDF]
Physical Review LettersWe report direct observations of surface waves from a stereo camera system along with concurrent measurements of wind speed during an expedition across the Southern Ocean in the austral winter aboard South African icebreaker S.A.~Agulhas~II. Records include water surface elevation across a range of wave conditions, spanning from early stages of wave ...

Ocean Meteorological Observations [PDF]
Nature, 1872 I PRESUME that anyone looking at the chart on page 43 of this week's NATURE, or reflecting on the circumstances under which barometric observations at sea are ordinarily taken, will agree with me that it would be wiser to give only two places of decimals, and not indicate a degree of refinement which the observations do not warrant.

Frontiers in Marine ScienceMonitoring the quality of marine water is crucial for ensuring the health and sustainability of marine ecosystems. The conventional monitoring approach involves manual sampling using a water sampler, followed by packaging the water samples in plastic ...
