A turn to the left speeds things up...

September 27, 2007
This afternoon we sampled the second phytoplankton bloom area for NOAA. While filtering water through a microfilter, and simultaneously manta trawling, we noticed a ghost net floating by. 'we immediately through our red marker buoy, hauled in the manta and turned around to try to relocate the ghost net. Although we were only a few hundred yards away from the buoy when we turned around, with the wind blowing 15-20 knots, we were unable to relocate the net. After finishing the plankton sampling, we made sail and are now close reaching under mainsail and genoa jib, bound for Hilo Hawaii, where we plan to arrive on the morning of October 1. We have turned left from our westward route and are now heading south. This affords an angle to the steady, strong northeast trade winds that our hybrid reasearch vessel finds particularly favorable. Before we made this course change, we were broad reaching downwind, and a particularly violent swell caused our mast to lurch and snap off the masthead light tower. We had to take the bosuns chair up to the top and cut it free. The sound of the engines are a distant memory as we sail along at 8-9 knots and charge our battery banks with a kilowatt of BP solar panels. We are making our own drinking water with a 12 volt reverse osmosis desalinization system using solar energy. The view of ORV Alguita attached to this log was taken before the panels were added to a roof built above the after deck. Alguita is now the only hybrid research vessel doing major studies on the high seas. Hopefully, more vessels will eventually follow suit and become more energy efficient. We look forward to the day when we pull into port and call for the vegetable oil tanker truck to come down to the dock and top off our fuel tanks.
Our noon position was 29 36 N, 153 24 W. Given the favorable winds and point of sail that keep us making between 8-9 knots, we believe our ETA Hilo will be the morning of Oct. 1.
Aloha from ORV Alguita

Septiembre 27 del 2007.
Esta tarde muestreamos la segunda muestra dentro del area de crecimietno acelerado (bloom) de fitoplancton para la NOAA. Mientras estabamos filtrando el agua atraves de un microfiltro y al mismo tiempo teniamos la manta filtrando dentro del mar, cuando nos dimos cuentra de una red fantasma (ghost net) que estaba flotando a un lado de nosotros. Inmediatamente marcamos el area enviando nuestra boya roja, tomamos la manta de regreso al barco y regresamos a localizar la red fantasma. Aunque estuvimos a solo unos cuantos metros de la boya, cuando dimos la vuelta con un viento soplando de 15-20 nudos, increiblemente fuimos incapaces de relocalizar la red. Despues de terminar la coleccion de muestra de placton, comenzamos a velear, usando la vela principal y foque genovesa y ahora estamos mas cerca de nuestro punto final, Hilo Hawaii. Nuestro plan de arrivo es en la manana de octubre primero. Dimos una vuelta a la izquierda de nuestra ruta hacia el oeste y ahora navegamos hacia el sur. Esto soporta un angulo estacionario, con vientos fuertes al norte que para nuestro barco hibrido de investigacion es bastante favorable. Antes de hacer este cambio de curso, estuvimos bajo fuertes vientos y sobre todo un fuerte oleaje que provoco que nuestro mastil perdiera la luz de su torre al desprenderse el bulbo. Tube que ponerme la silla para escalar, subir y cortar el bulbo para su total desprendimiento. El sonido de las maquinas son una recuerdo pasado ya que vamos veleando entre 8 y 9 nudos y con la carga de nuestro banco de baterias con un kilowatage de BP paneles solares. Estamos produciendo nuestra agua para tomar usando la energia solar alamacenada en una pila de 12 voltios y un sistema desalinizador usando osmosis reversa. Una fotografia de una vista desde lo alto del mastil , antes de poner los paneles solares en la parte de arriva sobre la popa, del del ORV Alguita se esta anexando a este correo. El Alguita es el unico barco hybrido de investigacion que por ahora, estra haciendo grandes estudios en alta mar. Esperamos que mas barcos eventualmente sigan nuestro camino de usar mas eficientemente la enegia. Ahora, miramos hacia el pasado, a el dia en que llenamos nuestros tanques de combustible de aceite vegetal, en el puerto.
Aloha desde el ORV Alguita.
Nuestra posicion fue 29 36 N, 153 24 W. Con vientos favorables y las velas en tal punto que permiten una velociada de 8 a 9 nudos, por lo que creemos que nuestra ETA Hilo sera en la manana del primero de octubre.

Hi my name is Shaelene Guerrero I go to George Washington high school on Guam.
And about the blog basically what is a ghost net used for because I never heard of it? And how long does it usually take you to get to where you want to go by boat?
I think the things that you are doing and experiencing is really neat and I would like to learn more about your experience....

Hi my name is Nico Evarola from George Washington High School and currently studying marine biology.
I was wondering what was the most interesting finding since your expedition began?

Schaelene,
A "ghost net" is the name used for a fishing net that was either discarded or lost at sea. The net continues to catch and kill marine life as it floats through the waterShaelene,

How long it takes to get somewhere in a sailboat is very dependant on the wind. Yesterday ORV Alguita was scheduled to arrive in Hilo on the 1st of October. Then the wind picked up from a more favorable angle- now the scheduled arrival time is the afternoon of September 30th.

Nico,
I will ask the crew tomorrow when they arrive in Hilo what the most interesting finding was on the entire trip. I would also like to ask that of you- of all of the experiences and findings that the crew shared what did you find to be the most interesting?
