CephBase:Testing Ideas for Cephalopod and Other Species-Level Databases
CephBase Testing Ideas Cephalopod Other Species-Level Databases
2015/8/5
This report shares our experience of what worked and what did not while developing CephBase (www.cephbase.dal.ca). We share our triumphs and failures as well as our vision for the future to help and e...
Observation, Hypothesis-Testing, and Discovery in Oceanography
Oceanography Hypothesis-Testi
2015/7/29
Discovery lies at the very heart of scientific endeavor. It heralds progress, the march of science in uncovering the mysteries of the world that surrounds us. But how do discoveries come about? "By ob...
Development of Miniature Full Flow and Model Pipeline Probes for Testing of Box Core Samples of Surficial Seabed Sediments
box core sampling of seabed sediments cyclic t-bar testing full flow penetrometers intact and remolded undrained shear strength t-bar and ball toroid and model pipeline testing
2014/11/4
The box corer is a relatively new tool used in the geotechnical community for collection of soft seabed sediments. Miniature full flow and model pipeline probes were developed as tools to characterize...
Threshold-driven shifts in two copepod species: Testing ecological theory with observational data
Threshold-driven shifts two copepod species Testing ecological theory observational data
2014/4/2
We used an observed abrupt shift in the dominance pattern of two coexisting copepod species in Müggelsee, a shallow eutrophic lake in Germany, to investigate mechanisms leading to this shift, by embed...
Testing an improved cymbal hydrophone
cymbal hydrophone sensitivity resonance frequency parallel connection frequency band
2011/9/13
Cymbal hydrophones have small volume and high sensitivity, but their reception is not stable enough, and their reception is in too narrow a frequency band. In order to overcome these inadequacies, the...
A method for testing drag-reduction on riblet surfaces based on the Spalding formula
Spalding formula riblet surface drag-reduction testing
2011/9/13
This paper presents a method based on the Spalding formula for testing drag-reduction on riblet surfaces. Its advantage lies in that it is more convenient and yields more precise data compared with te...
On the Interpretation of Ocean Current Spectra, Part II：Testing Dynamical Hypotheses
Ocean Current Spectra Dynamical Hypotheses
2009/2/23
Three examples are chosen to illustrate how the several spectrum representations in Part 1 can be used to test whether a proposed dynamical mechanism is supported by a given set of observations. The e...
Initial Testing of a Numerical Ocean Circulation Model Using a Hybrid (Quasi-Isopycnic) Vertical Coordinate
Initial Testing Hybrid (Quasi-Isopycnic) Vertical Coordinate Numerical Ocean Circulation Model
2009/2/9
An ocean circulation model, developed for the study of mesoscale to gyre-scale circulation and heat transport, is described and tested. The model employs density as vertical coordinate except in the i...
Testing a Dynamical Model for Mid-Latitude Sea Surface Temperature Anomalies
sea surface temperature Dynamical Model oceanic mixed layer
2009/2/5
A slab model of the oceanic mixed layer is used to predict the statistical characteristics of the sea surface temperature anomalies that are forced by day-to-day changes in air-sea fluxes in the prese...

2009/1/10
The asynchronous coupling schemes used in the seasonal, coupled atmosphere–ocean general circulation models (A/O GCMs) of Manabe et al. 1979 and Washington et al. 1980 are tested in the seasonal, coup...
Computational Efficiency and Accuracy of Methods for Asynchronously Coupling Atmosphere–Ocean Climate Models. Part I：Testing with a Mean Annual Model
Computational Efficiency Atmosphere–Ocean Climate Mean Annual Model
2009/1/10
Using the mean annual, globally-averaged, coupled atmosphere–ocean energy balance model of Harvey and Schneider, the effect on the transient climate response to a step function solar constant increase...
