Sea surface temperature variability in the Florida Keys and its relationship to coral cover

Louis Stokes Alliances for Minority Participation AND Program Evaluation

Hallock P, Hu C, Muller FE, Soto IM.
GSID: 3HOfmoNDttYJ
IM Soto, FE Muller Karger, P Hallock, C Hu - Journal of Marine Biology, 2011 - hindawi.com

The hypothesis that moderate variability in Sea Surface Temperature (SST) is associated with higher coral cover and slower rates of decline of coral cover within the Florida Keys National Marine Sanctuary (FKNMS) was examined. Synoptic SST time series covering...

Resonant transducers for solid-state plasma density modulation.

The Review of scientific instruments

Hallock GA, Meier MA.
PMID: 27131695
Rev Sci Instrum. 2016 Apr;87(4):044902. doi: 10.1063/1.4947507.

We have developed transducers capable of modulating the plasma density and plasma density gradients in indium antimonide. These transducers make use of piezoelectric drivers to excite acoustic pressure resonance at 3λ/2, generating large amplitude standing waves and plasma density...

Statistical characterization of thermally evaporated rough CaF2 films.

Physical review. E, Statistical, nonlinear, and soft matter physics

Luhman DR, Hallock RB.
PMID: 15600627
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Nov;70(5):051606. doi: 10.1103/PhysRevE.70.051606. Epub 2004 Nov 19.

Thermal deposition of CaF2 onto a glass substrate creates a nanoscale rough surface. A series of samples with differing nominal CaF2 film thicknesses have been fabricated, and the topography has been investigated using atomic force microscopy. Measured values for...

Optical forces between metallic particles.

Proceedings of the National Academy of Sciences of the United States of America

Hallock AJ, Redmond PL, Brus LE.
PMID: 15647359
Proc Natl Acad Sci U S A. 2005 Feb 01;102(5):1280-4. doi: 10.1073/pnas.0408604101. Epub 2005 Jan 12.

We calculate the optical attractive forces that occur between 30-nm Au or Ag nanocrystals when irradiated at visible wavelengths. These forces show resonances at dipolar plasmon wavelengths, similar to resonances in the near-field electromagnetic intensities. At MW/cm2 intensities, optical...

Kosterlitz-Thouless transition for 4He films adsorbed to rough surfaces.

Physical review letters

Luhman DR, Hallock RB.
PMID: 15447205
Phys Rev Lett. 2004 Aug 20;93(8):086106. doi: 10.1103/PhysRevLett.93.086106. Epub 2004 Aug 19.

We report the study of adsorption isotherms of 4He on several well characterized rough CaF2 surfaces using a quartz crystal microbalance technique at 1.672 K. The signature of decoupled mass observed on crossing the Kosterlitz-Thouless transition as a function...

Evidence for power-law dominated noise in vacuum deposited CaF2.

Physical review letters

Luhman DR, Hallock RB.
PMID: 15245036
Phys Rev Lett. 2004 Jun 25;92(25):256102. doi: 10.1103/PhysRevLett.92.256102. Epub 2004 Jun 24.

We have studied the surface roughness of CaF2 vacuum deposited on glass using atomic force microscopy for film coverages spanning an order of magnitude. We find the roughness exponent alpha=0.88+/-0.03, the growth exponent beta=0.75+/-0.03, and the dynamic exponent z=alpha/beta=1.17+/-0.06....

Two approaches to the star mapping problem for space vehicle attitude determination.

Applied optics

Gorstein M, Hallock JN, Valge J.
PMID: 20076194
Appl Opt. 1970 Feb 01;9(2):351-8. doi: 10.1364/AO.9.000351.

The use of gimballed and strapped down star trackers for spacecraft attitude determination is a well-developed technology, but it presupposes some restricted degree of knowledge about the star positions and usually requires a special maneuver to obtain a favorable...

Unexpected Mass Decoupling for 3He-4He Films on a Solid Hydrogen Substrate.

Physical review letters

Finley PT, Ebey PS, Hallock RB.
PMID: 17678100
Phys Rev Lett. 2007 Jun 29;98(26):265301. doi: 10.1103/PhysRevLett.98.265301. Epub 2007 Jun 25.

Quartz oscillator measurements reveal new behavior in 3He-4He mixture films on a H2 substrate. For mixture films of total coverage greater than one monolayer, in addition to the expected Kosterlitz-Thouless transition, a second mass decoupling event is observed, which...
