Q. and A. on the Nitrogen Cycle

You mentioned that the ratio of nitrogen to phosphorus is lower in the area in which you work compared to the oceanic average. Is this due to a biological process? I mean, does the ratio of phosphorus to nitrogen determine which microbes are present, or do the organisms manipulate the ratios to create this environment for themselves?

Megan Banner, Kingston, R.I.

This is a difficult question that oceanographers are actively studying. The nitrogen to phosphorus ratio (N:P) in the ocean is determined by the organisms that live there and water movement between the ocean basins. The N:P ratio, in turn, can influence which organisms are present. In the eastern tropical South Pacific, N:P is low because denitrifying bacteria remove nitrogen without also removing phosphorus. However, the low nitrogen to phosphorus ratio that is set up by this process probably also influences which photosynthetic organisms, requiring nitrogen and phosphorus, live in the surface waters.

This is a great question about the possibility of hydrothermal vents as sources of nitrogen to the deep ocean. In general, hydrothermal vent fluids have very low concentrations of dissolved nitrogen compounds. Vent systems near coasts, however, have measurable concentrations of nitrogen. These emissions are small relative to total nitrogen inputs to the ocean, likely accounting for less than 1 percent.

Ben raises a good point about what the ecosystem level effects of an imbalanced nitrogen budget would be. As I pointed out in my first post , the apparent budget imbalance in the nitrogen cycle is probably a result of bad accounting, rather than an actual imbalance in nitrogen inputs and losses in the ocean. An analogy might be your own bank account. Just because the balance in your account is staying constant, it is still helpful to know when and how much money is coming in and going out. Nitrogen inputs and losses in the ocean appear to have been balanced through most of the geologic record, so we don’t really know what the consequences of a grossly imbalanced budget would be.

“Some estimates of the amount of nitrogen leaving the ocean exceed estimates of the amount of nitrogen coming in by several hundred teragrams (that’s one billion kilograms) per year.” This is a meaningless figure without context. Considering that the estimated amount of ocean water is several hundred quintillion (quintillion = 1 million x 1 trillion) gallons, ’some estimates’ (whatever that means) are in the order of magnitude of 1 gram nitrogen deficit per million gallons of water, or if you prefer, in the range of 0.25 parts per billion. Kudos on studying the marine nitrogen cycle, but please use more meaningful numbers to illustrate your point.

Fishing Report: May 27, 2011

No coho fishing is opened yet off the Central Oregon coast, and coho fishing is banned summer-long in the ocean off Southern Oregon. Sport crabbers are allowed on the ocean, and bay crabbing has improved thanks to improved salinity levels in bays.

Lincoln City is located adjacent to Highway #101 in the western state of Oregon .  The town itself attracts visitors all year long because of the temperate climates and numerous activities to enjoy. Your family, with children and elders alike, will find this city not only interesting, but fun.  Years ago Lincoln City was not as large as it is today simply because it is now comprised of 5 towns put together.

Needless to say,  Lincoln City draws people because of the Pacific Ocean access that sits awaiting your visitation.  Free parking nearby Lincoln Beach invite you and your children to walk the camel colored sandy shores while playing with the gentle waves too.  The vastness of the sea mesmerizes many, however a newcomber must be aware of the “sneaker waves” that can arrive at anytime, disrupting ones, once known solid footing.  They are known by locals and signs are posted for visitors to this seemingly peaceful Pacific Ocean.  Water temperatures require dipping unless you have a wet suit since the degrees might be a chilly 60 during a warming current.

Windsurfers, beach/sand surfers are quite often seen on the beach drifting with the air and water flows.  The sometimes strange equipment will attract children of all ages to watch those activities wanting to experience them as well.  Local businesses accommodate those requests with gear and lessons for the purchase price of both. 

It is the experienced and well schooled board surfers that enter into the frigid waters who first learn basic training skills.  Water is to be respected, so talk to merchants to discover the answers to your questions before diving into the Pacific Ocean.  Waves can swirl and have an under tow as well, which could redirect your original plans to swim in one direction.  A smart swimmer learns and heeds warnings to not swim alone and be aware of some dangers while in the sea enjoying the surf.

Flying kites dot the sky using the gentle winds to have many hours of pleasure and exercise as well.  Make sure you get one for everyone so that pasttime can be enjoyed by all. 

Photography is a favorite hobby for many who visit Lincoln Beach since the back drop of the endless horizon and mountains, surrounding the ocean are often captured.  It is rare to have snow fall on the distant mountain peaks during the winter, however has been seen even on the Lincoln Beach shore.
