Banggai Cardinalfish pair paternal mouthbrooding and female courtship dance

Smithsonian Marine Station at Fort Pierce
A pair of Banggai Cardinalfish at the Smithsonian Marine Ecosystems Exhibit in Fort Pierce, FL. The male is seen with a mouthful of eggs and the female can be seen exhibiting her courtship dance several times.

Catshark embryo developing inside egg case! (mermaid's purse)

Smithsonian Marine Station at Fort Pierce
Here's a look at our catshark (also known as dogfish) developing inside its egg! The round sphere is the yolk, which it will feed on until it gets strong enough to hatch out of the egg case, also known as a mermaids purse.

Umbrella Coral (Xenia sp.)

Smithsonian Marine Station at Fort Pierce
Umbrella corals pulse rhythmically during respiration and feeding, mimicking the swimming motion of a jellyfish in open water. The pumping of coral polyps is often misinterpreted as planktonic prey capture, but Xenia actually trap dissolved organic compounds in their mucous nets. These corals are called Xenia (Greek for "hospitality") because the pulsing resembles many hands waving hello. http://www.facebook.com/home.php#!/SmithsonianSMS

Five Statues form Ain Ghazal, Jordan - No Music

Smithsonian Museum Conservation Institute
Smithsonian Museum Conservation Institute staff preserve 9000 year old statues unearthed during road construction in Jordan. Extraordinarily rare plaster statues dating from around 6500 B.C. were discovered in 1985 at the Neolithic site of 'Ain Ghazal, Jordan, on the outskirts of the capitol city Amman. Because of the fragility of the lime plaster, the entire contents of the pit containing the statues were encased in aluminum foil, polyurethane foam, and a wooden crate and sent to the Smithsonian Institution for a seven-year process of laboratory excavation and conservation treatment. The group includes two standing figures measuring around 1 meter in height and three unusual two-headed busts. Filming was done on five occasions from 1990 to 1996 before exhibition of the statues at the Smithsonian's Arthur M. Sackler Gallery in 1996-1997 and their return to Jordan for display at the Jordanian Archaeological Museum on the Citadel in Amman.

MapArt OpenSource Viewer Presentation

Smithsonian Museum Conservation Institute
MapArt OpenSource Viewer: A Layered Solution for Viewing Scientific Imagery E. Keats Webb, Digital Imaging Specialist at the Smithsonian Museum Conservation Institute Reed Tomlinson, Chief Technology Officer for MapArt Systems. The MapArt OpenSource Viewer uses GIS based software to layer multiple images of a cultural heritage object in a dynamic and accessible interface allowing conservators and researchers the ability to virtually "walk through" an object in a multispectral and mulitdimensional way.

Tri Color Images in ds9

Smithsonian Astrophysical Observatory
Here we show how to load and manipulate three color images, or tri-color images, into ds9. Often these are used to show false energy colors; however, in this demo we also show how they can be used to see source temporal varability.

Chandra Aperture Photometry

Smithsonian Astrophysical Observatory
In this demo we show how to get photometric results from a Chandra observation, including net counts, rate, photon fluxes, model independent fluxes, and model dependent fluxes. Using the new srcflux tool, the flux computed in various ways is computed directly from within ds9.

Using multiple frames with ds9

Smithsonian Astrophysical Observatory
Shows how to load multiple datasets into multiple frames, switch between, match frames on wcs, and use the crosshair to identify same point in all frames.

Extracting Spectra, Light Curves, and Radial Profiles within ds9

Smithsonian Astrophysical Observatory
Using the CIAO :: Histogram menu, users can extract simple spectra, make light curves, and even create radial profiles without having to know all the behind the scenes CIAO syntax.

An Introduction to the ds9 catalog tool

Smithsonian Astrophysical Observatory
The ds9 catalog tool provides a gateway to many source catalogs and provides powerful tools to visualize and interact with the catalog data.
