scientists participated on these panels
as well, and in evening sessions they
had an opportunity to share their career
paths, past projects, and current research
interests. Additionally, feder...
"Can I really do this?!" Enthusiasm and doubt surrounded the junior women at the opening reception of the Pattullo Conference. As in other science and engineering fields, real and perceived challenges...
Mix it Up, Mix it Down: Intriguing Implications of Ocean Layering
Ocean Layering Intriguing
2015/7/3
Using a physical simulation, we explore the vertical density structure within the ocean and how layering (density stratification) controls water motion, impedes nutrient transport, and regulates biolo...
Teaching Strategies that Hook Classroom Learners
Hook Classroom Learners Teaching Strategies
2015/7/3
It should not be a surprise to learn that most earth science/oceanography and other STEM (Science, Technology, Engineering, Mathematics) faculty teach classes the same way they were taught, typically ...
HERMES Hotspot Ecosystem Research on the Margins of European Seas
European Seas Ecosystem Research
2015/7/3
The various teams within the HERMES
partnership supported each other, forged
new and productive collaborations,
broke new ground in interdisciplinary
science, and pulled together to attain
t...
Continuous monitoring of water-column
and near-bottom hydrosedimentary processes in the
Mediterranean Sea over the last 15 years has resulted in a novel
view of the functioning of this land-lock...
development of an Autonomous Aquarium System for Maintaining deep corals
corals Aquarium System
2015/7/3
Keeping deep corals alive under optimum water temperature and quality
conditions is not an easy task. It is important to achieve a balance among
a high-water renewal rate, constant water temperatu...
ANALYSES OF MULTI-YEAR SYNTHETIC APERTURE RADAR IMAGERY OF DRY-FALLEN INTERTIDAL FLATS
Synthetic Aperture Radar intertidal flats
2015/5/7
We analyzed a great deal of high-resolution Synthetic Aperture Radar (SAR) data of dry-fallen intertidal flats in the German Wadden Sea with respect to the imaging of sediments, macrophytes, and mus...
基于声波方程的有限频伴随状态法初至波旅行时层析
初至波旅行时层析 波路径 核函数
2015/5/15
根据有限频理论,对于特定震相的观测信息,不仅射线路径上的介质对该信息具有影响,路径以外的其它区域对接收信息也具有影响,这种影响可以用核函数来表达。传统核函数的计算是基于"波路径"的,计算繁琐且效率低。而基于射线理论的伴随状态法虽然可以在很大程度上提高反演效率,却没有考虑地震波传播的有限频特性,这就导致了反演过程中低波数信息的缺失。本文基于伴随状态法,同时考虑地震波传播的有限频特性,研究并实现了基于...
Stoichiometric imbalance in rates of nitrogen and phosphorus retention, storage, and recycling can perpetuate nitrogen deficiency in highly-productive reservoirs
nitrogen phosphorus retention storage
2014/11/28
We measured the nutrient stoichiometry of inputs, outputs, retention, storage, and recycling in three seasonally
nitrogen (N)-deficient reservoirs by incorporating watershed mass balances with measur...
Recent changes in production in oligotrophic Uinta Mountain lakes, Utah, identified using paleolimnology
oligotrophic Uinta Mountain lakes Utah
2014/11/28
We use multiple proxies from lake sediment records of six remote alpine lakes in the Uinta Mountains, Utah,
to investigate primary production and potential drivers of changes in trophic status over t...
Photosynthetic protein stoichiometry and photophysiology in the high latitude North Atlantic
protein stoichiometry photophysiology
2014/11/28
Iron availability influences phytoplankton physiology and growth over more than one-third of the surface
oceans, with recent evidence even indicating iron stress during and following the latter stage...
Nitrate uptake by foraminifera and use in conjunction with endobionts under anoxic conditions
endobionts anoxic conditions
2014/11/28
Among eukaryotes, some benthic foraminiferal species have been reported to be capable of nitrate respiration,
although little is known about their denitrification processes. In this study, we incubat...
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...
