Tonight is a full moon , so today we have a start of a spring tide. Higher highs, Lower lows.  (Posted1 month ago ) “Together, the gravitational pull of the moon and the sun affect the Earth’s tides on a monthly basis. When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tides. One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. During each lunar month, two sets of spring and two sets of neap tides occur (Sumich, J.L., 1996).”  (Brought to you by the NOAA Ocean Service Education)  http://oceanservice.noaa.gov/education/kits/tides/media/supp_tide06a.html

brackrhamphotheca: Homosexual Fish More Attractive to Females by Elizabeth Norton Females of many species are attracted to large, conspicuous males. But among animals that mate with many partners, a male that manages to score with one female can increase his chances of attracting others even if he’s nothing much to look at. New research shows that, in some fish at least, smaller, less flashy males can also win female mates by flirting with larger males. Working with the tropical freshwater fish Poecilia mexicana, researchers showed female fish video footage of small, drab-colored males “nipping” the genital openings of larger, brightly colored males—an action that precedes mating in opposite-sex fish pairs. After witnessing this behavior, the female fish indicated their awakened interest by spending more time swimming near the images of the formerly unimpressive males, the researchers report online today in Biology Letters. The finding suggests that, far from being an evolutionary dead end, homosexual behavior can enhance a male’s ability to pass on his genes by attracting females that wouldn’t be interested in him otherwise.

Okay. Elections are over and the school semester is coming to an end, so finally I have some breathing room. I am going to be creating a couple new tabs with goodies as well as theme changes: jacque cousteau video page   Fellow ocean blogs Other blogs I have created: Marine Conservationists United, Here to there.  Changing the Intertidal zone/beach page. (lots of new photos/neat species).  Modifying blog topics:   “More original blogs less re-blogs”.  Action links.  How to create change in your local community.  Oceanography textbook concepts/art/figures.  Ideas: Identifying beach types and beach parts.

Have you ever wondered what the water temperature off the Kamchatka Peninsula is?  What about the wind speed in the Andaman Sea?  Or maybe you’re losing sleep over the chlorophyll levels in the South Pacific.  Fortunately, all of that information –- and 450 million other data points collected from oceanographic instruments around the world –- is freely and easily accessible thanks to the Marinexplore project.

2012 UCSB Washburn Lab, ARC Program

This is a Wave Pressure Data Logger, which is made in the UCSB Washburn lab.

This instrument detects changes in wave pressures from changing wave heights.  It measures four times a second in absolute water pressure.  This high sampling rat is needed to capture such intricate pressure changes in surface waves.  It is powered by four D-cell Batteries, which and run up to three months.  Data is stored on to a 2GB SD card.  

The test button verifies the battery voltage, configuration files, recording pressure, and connections.  The start and stop botton record the start and stop times of sampling.

The instrument is protected with clear PVC tubing, and rubber o-rings prevent water leakage.
