The island Tristan da Cunha is located in the South Atlantic Anomaly, and until recently the area has been one of the largest gaps in the global geomagnetic observatory network. As part of the Danish project SAADAN we set up a geomagnetic observatory on the island. Here we report on how we established the observatory in 2009 and on its operation in 2010.

We present high and moderate spectral resolution spectroscopy of diffuse ionized gas (DIG) emission in the halo of NGC 891. The data were obtained with the SparsePak integral field unit at the WIYN Observatory. The wavelength coverage includes the [N II]λλ 6548, 6583, Hα, and [S II]λλ 6716, 6731 emission lines. Position-velocity (PV) diagrams, constructed using spectra extracted from four Spars...

The methods and software interfaces used by ocean observatory operators and scientist users to access data generated by sensors and instruments attached to research observatories vary widely from facility to facility. The tools used to access instrument metadata and to control various instrument functions are also variable between observatories. An effort has begun in the US to define software ...
