This paper uses dissipation values derived from UARS/HRDI observations in a recently published diurnal-tide model. These model structures compare quite well with the UARS/HRDI observations with respect to the annual variation of the diurnal tidal amplitudes and the size of the amplitudes themselves. It is suggested that the annual variation of atmospheric dissipation in the mesosphere-lower the...

Fucus serratus is a common brown algae which occurs all round the British coast. At low tide male and female plants release antheridia and oogonia into the seawater (1) and fertilization occurs as the tide rises causing release of the encapsulated spermatozoa and eggs. In contrast to mammalian sperm which have been widely studied very little is known about the mechanism of activation of the spe...

Interferometric synthetic aperture radar (InSAR) observations of ice-shelf flow contain ocean-tide and atmospheric-pressure signals. A model-based correction can be applied, but this method is limited by its dependency upon model accuracy, which in remote regions can be uncertain. Here we describe a method to determine two-dimensional ice-shelf flow vectors independently of model predictions of...

The widespread distribution of fruiting myxobacteria in the soil is fairly well known; however, there have never been reports on these bacteria isolated from the sand of an ocean beach. To establish the presence of myxobacteria in this possible habitat, samples of sand from the high tide marks of four South Carolina beaches were collected (see Table 1). One of the samples, 11, differed from the...
