Anybody else disgusted by reporters standing on a beach in a hurricane, telling everyone else to flee?

Journalist lose credibility that way. Cause people to think that they are going for hype. And make other believe that if the reporter can do it, then so can they.
@ Bill: Not when they cut to a live shot every 15 minutes.



Answer
TV is a visual medium.
Sure. They can sit in their nice well-lit studio with their weather maps and satalite pictures and show you the clouds from orbit.... But that's not going to tell the story.
You might not believe it's that bad if you're just seeing peaceful pictures from space. That's why they send a crew out to show you... Visual Medium. I don't know how many stories don't have the right impact because a reporter forgets to SHOW things.

They're not doing it for hype. They're doing it because it's their job to show YOU what's happening. Show you how high the water is. How fast the wind is blowing.
They've got someone talking to them deciding just how long to stay out there. The reporter and crew aren't going to stay if they're not safe. They're going to be talking to someone in the studio watching weather info so they can get out before they can't go anymore.
And besides....
They don't have as much to move out of the way. They've got a truck, a camera and maybe a shelter. When the shot goes off for the last time, they're out of there in minutes. Less than five if they're good... And they're not sending someone out there if they don't know what they're doing.

Is there a difference in salinity between sheltered and exposed coastlines?

Please Help, it's for Year 13 Bio coursework so in as much detail a possible please!


Answer
The exposed coasts are characterised by great mobility and consequently the associated problems can also be severe. Management of such shorelines requires great care.
These types of coastal profiles typically occur in connection with coastlines bordering medium large to large water bodies with dimensions from 100 km and upwards, storm wave climates with Hs,12h/y larger than 3m, micro to moderate tidal regimes, and moderate to macro storm surge regimes. There will often be a positive correlation between onshore wind speeds/wave heights and storm surge
The exposed littoral coast is characterised by a wide sandy beach and a wide shoreface with up to three bars; the coast can consists of dunes or cliffs.

Typical examples of exposed coastal profiles are found along the European coasts bordering the North Sea, the Atlantic and to some extent the Mediterranean and the North- and the South American coasts bordering the Atlantic and the Pacific Ocean

Sheltered or The protected coast will be characterised by a narrow beach or the complete lack of a sandy beach. The shoreface will be narrow and without any bars; the coast is often covered with vegetation right out to the beach and sometimes it is marshy with only very low cliff-like scars in the coastal formations. This type of coast occurs under arctic, temperate and subtropical conditions.

This type of coast is normally seen in connection with coastlines out to small bodies of water, for example fjords, estuaries and lagoons with typical dimensions of less than 10 km. However, such coasts can also occur out to larger bodies of water if one or more of the following conditions are fulfilled:

The wind and wave climate is mild
The geology of the area has provided a very shallow nearshore zone, which protects the shore against severe wave action
Strong onshore winds are correlated with low water (negative surge).The protected coast will normally not erode, but it can be exposed to flooding. Protected coasts will normally be of poor recreational value.

From above points we can say that..the exposed as the name says..is more exposed to the waters ..so the salinity is more when compared to the sheltered..which are contacted with salt water only in case of high tides or floods...
