Temp, sal, O2, velocity, heading from cruise LIS0507 Dataset Description: <p>Physical data from the LIS0507 cruise recorded by CTD and ADCP. Note that temperature, salinity, and oxygen concentration values are from CTD casts (averaged for depth of water) and not from the niskin bottles used to collect samples for DNA analysis. There is a lag in time and some drift of reaserch vessel between the two, since the niskin bottles were not on the CTD itself.</p>

Testing hypotheses about diversity, gene flow, and effective population size in marine planktonic ciliates

Testing hypotheses about diversity, gene flow, and effective population size in marine planktonic ciliates
<p>The microbial ecologist Tom Fenchel recently said, “The decoupling of molecular and classical (including experimental) approaches to environmental microbiology has not been fruitful and it represents one of the most important challenges for the field in the coming years.” (Fenchel 2005). Classical approaches center on the centuries-old tradition of describing individual species via meticulous observation and analysis to generate monographs, such as is done for plants and animals. Unfortunately, the rush to new molecular techniques has sometimes ignored this tradition, with claims about new lineages never seen before and reports of staggering diversity of microbial eukaryotes based on environmental DNA samples not backed up by even the most elementary microscopic observations.</p>
<p>In the face of this disconnect between the traditional and the molecular, we propose a marriage of the two approaches in the study of marine ciliate diversity and gene flow. Our own data show that in some clades of planktonic ciliates (Strombidiidae) there is indeed a high level of molecular diversity underlying a relatively small number of morphospecies. In other clades (some choreotrichs), the opposite appears to be true, with morphological heterogeneity underlain by apparently clonal lines, based on molecular data. Currently, we do not understand what sustains diversity in some clades; nor do we know why other clades show low diversity. But this problem is amenable to both experimental and observational approaches.</p>
<p>This proposal uses a two-pronged approach, combining molecular (clone libraries, DGGE,FISH) and traditional (light microscopy) techniques to address three broad questions:<br />
<b>i.</b> What are the most important physical and biological factors that affect distribution and diversity of planktonic marine ciliates?<br />
<b>ii.</b> What is the effective population size for marine ciliate populations, and how does this compare to census population sizes?<br />
<b>iii.</b> How well do traditional morphological descriptions of ciliate species fare when compared with molecular characterizations?</p>
<p>Using a combination of molecular and microscopy methods, we will address these questions in coastal planktonic ciliates. Analyses of the resulting data will yield insights into the nature of ciliate species and patterns of gene flow within the North Atlantic.</p>

Acoustic Doppler Current Profiler
Acoustic Doppler Current Profiler
PI Supplied Instrument Name: Acoustic Doppler Current Profiler Instrument Name: Acoustic Doppler Current Profiler Instrument Short Name:ADCP Instrument Description: The ADCP measures water currents with sound, using a principle of sound waves called the Doppler effect. A sound wave has a higher frequency, or pitch, when it moves to you than when it moves away. You hear the Doppler effect in action when a car speeds past with a characteristic building of sound that fades when the car passes. The ADCP works by transmitting "pings" of sound at a constant frequency into the water. (The pings are so highly pitched that humans and even dolphins can't hear them.) As the sound waves travel, they ricochet off particles suspended in the moving water, and reflect back to the instrument. Due to the Doppler effect, sound waves bounced back from a particle moving away from the profiler have a slightly lowered frequency when they return. Particles moving toward the instrument send back higher frequency waves. The difference in frequency between the waves the profiler sends out and the waves it receives is called the Doppler shift. The instrument uses this shift to calculate how fast the particle and the water around it are moving. Sound waves that hit particles far from the profiler take longer to come back than waves that strike close by. By measuring the time it takes for the waves to bounce back and the Doppler shift, the profiler can measure current speed at many different depths with each series of pings.
