Effects of salinity on specific gravity and viability of eggs of a North American minnow (Cyprinidae)

open access: yesScientia Marina, 2009
The influence of salinity on survival, specific gravity, and size of eggs of the endangered Hybognathus amarus (Rio Grande silvery minnow) was studied to provide insight into factors affecting their potential dispersal and fate.

The Buoyancy of the Sun-fish [PDF]

open access: yesNature, 1922
ABOUT the end of August numbers of sun-fish (Orthagoriscus mola) make their appearance off the north coast of Ireland floating passively on the surface of the sea. The positive buoyancy, while not so great as to prevent the fish from submerging when attacked, constitutes a constant upward drag which brings it back to the surface as soon as it stops ...

Control of a Buoyancy-Based Pilot Underwater Lifting Body [PDF]

open access: yesModeling, Identification and Control, 2010
This paper is about position control of a specific small-scale pilot underwater lifting body where the lifting force stems from buoyancy adjusted with an air pocket in the lifting body.

Entrainment Makes Pollution More Likely to Weaken Deep Convective Updrafts Than Invigorate Them

open access: yesGeophysical Research Letters, 2023
Are the results of aerosol invigoration studies that neglect entrainment valid for diluted deep convective clouds? We address this question by applying an entraining parcel model to soundings from tropical and midlatitude convective environments, wherein

Experimental study on influences of leakage of confined water on buoyancy of underground structures

open access: yesYantu gongcheng xuebao, 2019
In order to solve the problem that the prediction of the buoyancy of underground structures in confined aquifer is inaccurate, a series of model tests on the impact of confined aquifer seepage on the buoyancy of underground structures are conducted.

Field Test on Buoyancy Variation of a Subsea Bottom-Supported Foundation Model

open access: yesJournal of Marine Science and Engineering, 2019
The bottom-supported foundation is the most important component of offshore platforms, as it provides the major support to the upper structure. The buoyancy of the bottom-supported foundation is a critical issue in platform design because it counteracts ...
