Ikaite precipitation by mixing of shoreline springs and lake water, Mono Lake, California, USA
J. L. Bischoff, S. Stine, R.J. Rosenbauer, J.A. Fitzpatrick, Thomas W. Stafford Jr.
1993, Geochimica et Cosmochimica Acta (57) 3855-3865
Metastable ikaite (CaCO3·6H2O) forms abundantly during winter months along the south shoreline of Mono Lake where shoreline springs mix with lake water. Ikaite precipitates because of its decreased solubility at low temperature and because of orthophosphate-ion inhibition of calcite and aragonite. During the spring some of the ikaite is transformed...

Distribution and abundance of Marbled Murrelets in Alaska
John F. Piatt, R. Glenn Ford
1993, The Condor (95) 662-669
Most seabirds breed in colonies on offshore islands, but throughout most of their range from California to Alaska Marbled Murrelets (Brachyramphus marmoratus) fly inland to nest on trees in old-growth coniferous forests. Some fraction of the murrelet population nests on the ground in Alaska. The relative distribution and abundance of...
Survival and pre-fledging body mass in juvenile emperor geese
Joel A. Schmutz
1993, The Condor (95) 222-225
A positive relationship exists between fledgling body mass and juvenile survival for some altricial (Krementz et al. 1989, Magrath 1991, Linden et al. 1992) and precocial (Owen and Black 1989, Longcore et al. 1991, Francis et al. 1992) species. Because the energetic demands of migration are high, physiologic condition may...

Behavioral ecology of black-legged kittiwakes during chick rearing in a failing colony
Bay D. Roberts, Scott A. Hatch
1993, The Condor (95) 330-342
Compared with their Atlantic counterparts, Black-legged Kittiwakes (Rissa tridactyla) in North Pacific colonies are notably unproductive. A large colony on Middleton Island, Alaska, has in most years since 1981 seen complete breeding failure and the population has declined by half. We compared parent-offspring behaviors in this colony during two years...

A.T. Morrison, A.J. Williams, M. Martini
1993, Conference Paper, Oceans '93: Engineering in harmony with the ocean: Proceedings (Vol. 3)
The BASS current meter can measure currents down to the millimeter per second range. Due to the dependence of zero offset on pressure, determining a sensor referenced velocity requires accurate in situ zeroing of the meter. Previously, flow was restricted during calibration by placing plastic bags around the acoustic volume....
