Water Cycle (Notes in spanish)

Los deshielos que se producen en los Andes Sudamericanos; Los Apalaches de Norteamérica; Los Alpes Europeos; Montañas Africanas como las Drakensberg y el Monte Kilimanjaro; El Himalaya y otros, pueden deberse a eventos cíclicos. Recordemos que la Edad de Hielo -en el Pleistoceno- terminó apenas 10 000 años atrás aproximadamente y en ése tiempo el hielo cubría casi el 30 % de la superficie de la tierra, desde entonces la tierra inició un muy lento, pero progresivo, calentamiento que llevó al clima y los océanos a una etapa que no es precisamente rara para nuestro planeta, porque existen evidencias paleoestratigráficas y paleoecológicas que consignan a El Niño (cuyo aumento en frecuencia e intensidad está asociado, según muchos, con el Calentamiento Global) como un evento que se ha presentado en múltiples oportunidades desde hace mucho tiempo atrás, situándose en el Mesozoico incluso (entre 200 y 135 millones de años atrás), en ésta Era la temperatura terrestre se mantenía alta, con intensas lluvias. Empero, el curso general del ciclo hidrológico nunca fue seriamente dañado por no existir el excesivo consumo y mal uso del elemento (visto desde una perspectiva humana). Más aún, el estado químico del agua debió permanecer más o menos estable y cuando sufrió alteraciones por polución tectónica o de otro origen tuvo los rangos adecuados de tiempo para reestablecerse.



Pero claro, desde La Primera Revolución Industrial (mitad del Siglo XVIII), el hombre ha tenido una progresiva y sistemática influencia en el estado del clima y los océanos. Hay suficiente evidencia para afirmar que el CG ha sido acelerado por la actividad industrial humana; pero, no hay sificiente evidencia que indique que sólo el ser humano haya provocado el CG, éste ha acelerado el evento,pero el curso natural igual se hubiera presentado porque el calentamiento de aire y océano no es algo nuevo en la Tierra y tampoco lo es el deterioro de la Capa de Ozono porque la emanación de HCl, F, CO, CO2, N, H2S, etc., por la actividad volcánica submarina y terrestre también afectaba esta capa natural del planeta.

En este contexto, el agua como recurso universal para la vida es, a la vez, el más afectado y el peor usado de todos los recursos, en general, los grandes establecimientos humanos se han formado sin tener una planificación en relación al agua, la explosión demográfica ha generado una necesidad de productos artificiales que han dañado seriamente (e irremediablemente en algunos puntos del planeta), los compuestos artificiales elavorados que actualmente fabrica el hombre son muy eficientes en este sentido, más aún porque son usados constantemente por millones de personas y en cualquier parte del planeta multiplicando los efectos dañinos.




El Calentamiento Global ha casi obligado a muchos científicos a generar ajustes en las fórmulas que permiten estimar impactos en el ecosistema Los últimos modelamientos propuestos para el Cambio Global (Kondratyev, 2003) toman en cuenta -de manera muy adecuada- ciclos biogeoquímicos, ciclos hidrológicos, climas, océanos, procesos demográficos y cambios antropogénicos.

The Impact of Climate Change

Ocean Ecologies and their Physical Habitats in a Changing Climate

The goal of the workshop is to bring together biologists studying ocean and polar ecologies; oceanographers, biogeochemists, and climate scientists studying the changing physical habitats; and mathematicians with ecological and physical expertise. The two-way feedback interactions between ocean ecological systems and their physical environments have the potential to dramatically impact both marine biodiversity, and the planetary response to the changing atmosphere. The types of mathematics used to model ecological and physical processes are typically quite different. One of the exciting aspects of this workshop, and a reason to run it at MBI, is that we anticipate interesting new mathematical challenges arising from combining these different approaches to focus on modeling the feedback interactions between the ecological and physical systems.
The workshop will focus on two main themes:

1. Polar and sea ice ecologies
2. Phytoplankton and the carbon cycle

These themes are particularly timely in that the impact of climate change on these systems has been quite pronounced. Moreover, these areas are further tied together through the interplay of a wide range of the length scales involved, from microscopic to many kilometers over oceanic regions. As with all aspects of mathematics and climate change, this is an emerging area, and part of the reason for running the workshop is to help identify the mathematical challenges and opportunities the emerging topics present.

Theme

Main Theme

Ocean Climate and Marine Ecosystems in the Western Pacific

Sub Theme

Ocean and Coastal Observation

- Innovative observational studies concerning physical or biogeochemical processes in coastal and marginal seas are needed. Development and assessment of instruments or observing systems (e.g. fixed in-situ, satellite, ferries, floats, gliders, HF Radar) which provide the data required for oceanic studies will be mentioned, too.

Ocean and Coastal Acidification

- Ocean acidification, caused by a rapid rise in anthropogenic emissions of carbon dioxide (CO2), is rapidly changing ocean chemistry. A cooperative researches and knowledge-sharing collaborations including regional networking programs for ocean acidification beyond geopolitical boundaries are desperately needed.

Climate Modeling and Prediction

- Recent developments in the coupled climate modeling, ensemble, prediction results and the understanding of the interactions between ocean and atmosphere.

Air-sea Interaction and Coupled Air-wave Sea Modeling and Prediction

- Under the influence of climate change, it is important to predict the changing trend of air-sea interactions from the frequency and strength of storms to the response of the thermal structure of the upper layer by observing and modeling the sea state.

Anthropogenic Impacts and Climate Change

- Ecosystem changes caused by anthropogenic impacts, such as eutrophication, chemical pollution, overfishing, hypoxia and habitat modification and how climate change influences anthropogenic impacts and ecosystem

Marine Remote Sensing

- Marine remote sensing provides a window on synoptic scales. It is the sole method to take a global view of marine biosphere and monitor the ocean environments as climate change, water quality, fishery, and species at risk.

Adaptation to Coastal Disasters Related to Climate Change

- Assessment of regional as well as global impacts of natural disasters related to the climate change and developments of natural disaster reduction and mitigation systems will be covered.

Paleoclimatology: Corals and Monsoon

- The past climatic records which are monsoons evolution and effects such as linkage between terrestrial and ocean records, and other records from trees, corals, sediments, glaciers and other natural or proxy sources.

Dynamics of Coral Reefs and Changing Forcings

- It is predicted that 15% of the world’s coral reefs are under imminent threat of joining the "Effectively Lost" category within the next 10-20 years. These predictions are based on observed trends over the past decade, on demographic increases in human population pressure, and assessments of the effectiveness of current management.

Sediment Dynamical Processes and Coastal Erosion

- Most of coastal countries have been suffering from natural and man-made coastal erosions. Sound coastal management integrating various areas and considering the effects of climate change as well as development of new technology for erosion control is prerequisite for sustainable development of coastal zone.

Marine Biogeochemistry

Understanding the biogeochemical cycling of materials (salt, carbon, nutrients, trace elements etc.) requires knowledge of their diverse sources and sinks, as well as their transport and chemical form in the ocean. Without this understanding, the impact of any resulting changes due to human activity in elemental cycling on marine ecosystems and the global carbon cycle cannot be meaningfully predicted.

Marine Biodiversity and Conservation

- Marine biodiversity in the Western Pacific, especially in the coral triangle, is highest in the world ocean providing a rich source of food and biomaterials. Yet, a significant number of marine organisms remain to be discovered and identified.

Climate Change Impacts on Fisheries

- The abundance, distribution of major fish species and fisheries, species composition in ecosystem, and some social issues on economy can be altered by the climate changes. It is important to describe the climate change impacts on fish and fisheries and discuss conservation measures for mitigation and preparation in fisheries.

Environmentally Sustainable Aquaculture

- The best way to mitigate impacts for environmental sustainable aquaculture is to utilize an organic aquaculture. It will provide eco-friendly guidance to improve the environmental performance of sustainable aquaculture.
