Bird flu reaches Africa

Nature reported that bird flu has hit Nigeria, where at least 40,000 chickens have died. It's the first time the disease has been reported in Africa. The arrival of H5N1 in Africa is a scenario experts have long dreaded, as poverty and lack of infrastructure make control much more difficult.

Index finger and tongue

This is another anecdote about different convention used by meteorologist and oceanographer when doing a measurement. In some cases, they usually use same instruments to measure meteorology or oceanography parameters, and the most popular instrument they usually used for practical purpose is index finger and tongue.

Meteorologist usually use the index finger to measure the wind by wetting it with the saliva (using the tongue) and held it up to the air. The coldest part of the wet finger indicated from where the wind blew.

On the other hand, oceanographer usually use index finger to measure salinity of sea water by dipping the index finger into sea water and licking it (using the tongue). More salty the finger, higher its salinity.

So, the different convention is: meteorologist made use of the index finger as a sensor and the tongue as a tool to make the sensor works, whereas oceanographer made use of the tongue as the sensor and the index finger as a tool to take the water sample.

Does this different convention become a problem for them? Of course not! after completing the measurement, they had lunch together and made use of their tongue to taste the meals :)

 

Hydropolis: The First Undersea Hotel

Currently under construction in Dubai, Hydropolis is the world's first luxury underwater hotel. It will include three elements: the land station, where guests will be welcomed, the connecting tunnel, which will transport people by train to the main area of the hotel, and the 220 suites within the submarine leisure complex. It is one of the largest contemporary construction projects in the world, covering an area of 260 hectares, about the size of London's Hyde Park.

Twenty meters below the surface of the Arabian Gulf, just off the Jumeirah Beach coastline in Dubai, the £300 million, 220-suite hotel is due to open at the end of 2007. Hydropolis is structured in three elements: the land station, the connecting tunnel, and the submarine complex.

Meteorologist vs Oceanographer

My colleague, a Biologist, getting confuse when reads an analysis written by me about the hydro-oceanographic condition in Seribu Islands. It was occured view years ago when we did a mariculture research together. She needs the hydro-oceanographic analysis to know the effect of oceanographic condition to the distribution of phyto-plankton. She has already calculated the population of phyto-plankton from some sample stations around the Seribu Islands, and to make a distribution analysis she needs my result.

The statement that makes her getting confuse is: "The dominant east wind -during the observation period- generates strong west surface current around the Kelapa Island" (words that makes her confuse are written in bold font). She gives me a question then: "How can east wind (from her understanding it means: "a wind which blows to the east") generating west current (while from her understanding it means: "a current which flows to the west").

Well, nothing wrong with the statement above actually, but you should know a fact about different convention between Meteorologist and Oceanographer when they talk about "direction". If Meteorologist said "east wind" it doesn't mean a wind which blows to the east, but it means a wind which blows from east to the west direction, while if Oceanographer said "west current" it means a current which flows to the west.

Why they have different convention, even though -based on history- some oceanographers (in the very begining of the development of ocean science) are also meteorologists?. Based on some articles this different convention occurs because of different point of view. On land, it is important to know from where the wind blows: any windbreak must be erected in this direction. Where the wind goes is of no consequence. At sea, the important information is where the current goes: a ship exposed to current drift has to stay well clear from obstacles downstream. Where the water comes from is irrelevant.

Does this different convention make problem to them? Of course no, so far they always live hand in hand in perfect harmony... :)

Are sea foods still good for you?

I know that a lot of people really like sea foods very much. And so far we also know that sea foods are good for our health because reach of protein and mineral.

Well, based on the facts, the statement above is right: "sea foods are good for us!" but with some conditions, especially environmental issues. Perhaps you still remember about "another Minamata disease" during 2004 in North Sulawesi. Some poor people around the Buyat Bay have suffered from a range of mysterious health problems including skin diseases, tremors, headaches, and unusual swellings on the neck, calves, wrist, buttocks and head (source: WALHI).

Or maybe you have heard also that Jakarta Bay has a very serious chemical and heavy metal pollution problem. Some reseacrhers said that the water pollution in Jakarta Bay, where the sources of pollution came from domestic and industry sectors, are very high and above the standard (source: BPLHD Jakarta).

I am prety sure that you can't find a lot of same water pollution problems as above in some Indonesian waters. Oh ya, just for your information, actually the cycle of pollution is very complex. The air pollution can also generate land and water pollution. This cycle occurs when the rain wash out the pollutant from the air onto land or surface water.

What is the relationship between "water pollution" and "sea foods"? Well, to discuss about this matter you should know about the terms "food chain" and "accumulation". Yup! we had gotten a lesson about food chain when in Junior High School. Below is the illustration about it (source: seafriends.org).

Heavy metals cannot be destroyed through biological degradation. Food chain makes the higher level predators accumulate them in their body from what they ate, and human as the highest level predator will accumulate them all in their body also from what they ate. Of course, the concentration of them in the human body is the highest.

Well, this article of course not aimed to make you avoid sea foods. Sea foods are good and always good as long as we can maintain the quality of the coast and sea environment. Reducing the sources of pollutant is still the best and cheapest way so far.

Oh ya, for your information, actually this case not only valid for sea foods, but also for vegetables and fruits and everything come from the land (agriculture). One of the main problem in agriculture is pesticide. This is one of the reason why some developed countries in Asia, USA and Europe banned vegetables and fruits from Asia (Thailand, Indonesia, etc).
