Rio Cañete: Birdwatching

A UNDC student and an expert Peruvian birdwatcher - Miguel Lezama - in the field at the Boca del Rio (RC00) site with UNDC students. The mouth of the rio Cañete is an important site for a variety of endemic and migratory species. Birds are a useful bioindicator species in that they are relatively easily observed and there presence gives a good indication of the health of an environment. The UNDC students received tuition with respect to spotting species and correctly identifying them.

Un estudiante de la UNDC y un experto observador de aves peruano - Miguel Lezama - en el campo en el sitio Boca del Río (RC00) con estudiantes de la UNDC. La desembocadura del río Cañete es un sitio importante para una variedad de especies endémicas y migratorias. Las aves son una especie bioindicadora útil, ya que son relativamente fáciles de observar y su presencia da una buena indicación de la salud de un medio ambiente. Los estudiantes de la UNDC recibieron formación sobre la detección de especies y su correcta identificación.

Rio Cañete: River sediments

UNDC staff and students prepare to collect sediment samples from the river bed at the Boca del Rio site (RC00B) under the guidance of M.Hunter (UCAM). Samples (100+gr.) were collected from the river bed and bank at all sites. The samples were sent to the SGS laboratory, in Lima, where they were pulverised and then analysed for the presence of heavy metals. A very small quantity was also brought back to the UK for analysis using a mass spectrometer. An identification of the likely mineral content in the sediments was also undertaken using a Munsell Soil colour chart which uses a mix of variables: colour, texture and appearance to provide an indication of the possible mineral content.

Tecnicos y estudiantes de la UNDC se preparan para recoger muestras de sedimentos del lecho del río en el emplazamiento de Boca del Río (RC00B) bajo la dirección de M.Hunter (UCAM). Se recogieron muestras (100+gr.) del lecho y la orilla del río en todos los sitios. Las muestras se enviaron al laboratorio SGS, en Lima, donde se pulverizaron y luego se analizaron para detectar la presencia de metales pesados. También se trajo al Reino Unido una cantidad muy pequeña para analizarla con un espectrómetro de masas. También se identificó el posible contenido mineral de los sedimentos utilizando una carta de colores Munsell para suelos que utiliza una mezcla de variables: color, textura y aspecto para proporcionar una indicación del posible contenido mineral.

Rio Cañete: Water sample analysis

Water samples are prepared for filtering to remove sediments and organic material. Some analytical tests require filtered water: heavy metals, aniones & cationes, and alkalinity while others do not: pesticides, coliformes and chemical oxygen demand.

Las muestras de agua se preparan para filtrarlas con el fin de eliminar sedimentos y materia orgánica. Algunas pruebas analíticas requieren agua filtrada: metales pesados, aniones y cationes, y alcalinidad, mientras que otras no: pesticidas, coliformes y demanda química de oxígeno.

Measuring river discharge

UNDC students are instructed in the use of the Geopump - a portable pump which can be used in the field off a battery or in the laboratory, to pump the water through a filter to remove sediment and organic material.

Se instruye a los estudiantes de la UNDC en el uso de la geobomba, una bomba portátil que puede utilizarse en el campo con una batería o en el laboratorio, para bombear el agua a través de un filtro y sacar los sedimentos y la materia orgánica de la muestra.

Measuring river discharge

The water samples are finalised by UNDC student Edwin Chuquispuma - some samples require filtering while the sample for heavy metals analysis must also be reduced to pH2 through the introduction of a few drops of nitric acid to prevent the metals adhering to the plastic bottle. All samples must be fully and clearly labelled. Strict health and safety laboratory protocols are followed at all times.

Las muestras de agua son finalizadas por el estudiante de la UNDC Edwin Chuquispuma - algunas muestras requieren ser filtradas mientras que la muestra para el análisis de metales pesados también debe ser reducida a pH2 mediante la introducción de unas gotas de ácido nítrico para evitar que los metales se adhieran a la botella de plástico. Todas las muestras deben etiquetarse completa y claramente. En el laboratorio se siguen en todo momento estrictos protocolos de salud y seguridad.

Measuring river discharge

In the field, a laboratory needed to improvised and set up each day to process the water samples. UCAM and UNDC staff members carried out the same sample preparation and analysis procedures, and followed the same protocols as they would have done in the laboratory.

Sobre el terreno, fue necesario improvisar y montar un laboratorio cada día para procesar las muestras de agua. Los docentes de la UCAM y la UNDC llevaron a cabo los mismos procedimientos de preparación y análisis de muestras, y siguieron los mismos protocolos que habrían seguido en el laboratorio.

Measuring river discharge

Rio Cañete: Water quality data collection

Water quality data has been collected at over 35 sites within the Cañete drainage basin. At each site water samples are collected so that they can be analysed for heavy metals, aniones and cationes, and chemical oxygen demand while at around half a dozen of the lowest sites closest to larger urban areas and the most intensive agricultural activity, the water samples are also analysed for pesticides and coliformes. Strict health & safety regulations and sample collection protocols are followed - as demonstrated in the photo by two UNDC students - at the river to ensure that the water samples are not contaminated at the moment of collection.

Se han recogido datos sobre la calidad del agua en más de 35 puntos de muestreo en la cuenca de drenaje del Cañete. En cada lugar se recogen muestras de agua para analizarlas en busca de metales pesados, aniones y cationes, y demanda química de oxígeno, mientras que en alrededor de media docena de los lugares más bajos y cercanos a las grandes zonas urbanas y a la actividad agrícola más intensiva, las muestras de agua también se recogan en busca de pesticidas y coliformes. En el río se siguen estrictas normas de salud y seguridad, y protocolos de recogida de muestras - como demuestran en la foto dos estudiantes de la UNDC - para garantizar que las muestras de agua no se contaminen en el momento de la recogida.

Measuring river discharge

Basic river characteristics are also recorded: width, average depth and average velocity so that an average discharge can be calculated for that site on that day at that time. In the photo, A.Pacheco (UNDC) uses a laser range finder to record the width of the channel at a point where it is impossible to cross the river.

También se registran las características básicas del río: la anchura, la profundidad media y la velocidad media, de modo que pueda calcularse la descarga media en ese lugar, ese día y a esa hora. En la foto, A.Pacheco de la UNDC usa un telémetro láser para registrar la anchura del canal en un punto donde es imposible cruzar el río.

Rio Cañete: Shrimp catching

Shrimps are best caught in the dark when the torches of the shrimp catchers illuminate the shrimps eyes, blind and paralyse them. Shrimp catching is a skill and the project employed expert shrimp catchers at each site to catch them. The catchers entered the river at dusk and worked their way upstream looking for the shrimp under rocks as they swam against the current. It commonly took around 2 hours for the catchers to collect the required number of shrimp. In the lower valley they are smaller (females) but plentiful while in the upper valley they are less common but larger (males). The photos below were taken just above San Jeronimo and just below the Huayllampi Fish Farm site (RC04). UNDC student Edwin Chuquispuma holds up a fine bagged male shrimp.

Los camarones se capturan mejor en la oscuridad, cuando las antorchas de los camaroneros iluminan los ojos de los camarones, los ciegan y los paralizan. La captura de camerones es una habilidad y el proyecto empleó a expertos camaroneros en cada lugar para capturarlas. Los camaroneros se adentraban en el río al anochecer y remontaban la corriente buscando las gambas bajo las rocas mientras nadaban contra la corriente. Por lo general, los pescadores tardaban unas dos horas en recoger el número necesario de gambas. En el valle inferior son más pequeñas (hembras) pero abundantes, mientras que en el valle superior son menos comunes pero más grandes (machos). Las fotos de abajo fueron tomadas justo arriba de San Jerónimo y justo debajo del sitio de la Piscigranja Huayllampi (RC04). El estudiante de la UNDC Edwin Chuquispuma sostiene un buen ejemplo macho embolsado.

Title: Analysis of bofedales and their health by applying machine learning to satellite images

Abstract: The project has 3 main objectives:

  1. Research and development of a tool which identifies bofedales structure from other vegetation, dessert, etc. - referenced as “bofedales identifier”.
  2. Research and development of a tool which classifies bofedales either as healthy or unhealthy - referenced as : “bofedales health classifier”
  3. Research and development of a tool which assesses the dynamics and the evolution of bofedales. The first two tools are based on Deep Learning (subset of Machine Learning). In particular using a specific type of Neural Network: Convolutional Neural Network (CNN) in order to classify the examined bofedales. The train set of the neural networks is composed of satellite images and the respective success rate of the classification procedure is validated on completely unseen images. The tool in the third part of the project features how to make use of the available time-series data of satellite images and calculates various indices such as NDVI, NDWI as a function of time. Techniques such as time-series forecasting are then further applied to the calculated values in order to examine how bofedales change and to forecast future dynamics. The technologies used in the development of the above mentioned tools are Python, Colab, TensorFlow, Google Earth Engine and Google Earth.

Title: Assessing Environmental Quality in the Rio Cañete Drainage Basin The Andean River Shrimp (Cryphiops caementarius) as a Bioindicator Species

Abstract: The Andean River Shrimp (Cryphiops caementarius) is an important economic and cultural resource. We propose that it can be used to assess water and environmental quality and better understand trace metal transfer, bioaccumulation and environmental impact in Andean rivers. This work is readily divided into four areas of study. Firstly, a comparative study of environmental quality using DNA barcoding along with biotic and diversity indices. Secondly, using the Andean River Shrimp, to measure the bioaccumulation of trace metals (using ICP-MS). Thirdly, to describe pathways of trophic transfer in the Rio Cañete using Andean River Shrimp diet alongside invertebrate and vegetative tissue analyses and, fourthly, to identify the impact of trace metal accumulation on this species and its environment.

Title: River Water Geochemistry: Cañete River

Abstract: This talk will look at the Cañete River Basin. After introducing the watershed we will look at the factors that affect river water chemistry including rainwater, groundwater, geology, mining and other anthropogenic factors. The geology of Peru is dominated by the eastward subduction of the Nazca plate under South America. This has given rise to the Andean Mountains which in turn supply the water for most of Western Peru. The geology in Cañete is dominated by predominately carbonate sedimentary rocks in the upper basin, giving way to younger igneous rocks associated with the active volcanic arc in the middle basin and the older intrusive Coastal Batholith at the coast. This gives the Cañete Basin its unique characteristics and beautiful scenery, it also controls the chemistry of the tributaries which in turn control the chemistry of the main river. Initial results from this project suggest that in general the water in the river is of a very high standard with very little contamination. The chemistry of the river, and its sediments is dominantly controlled by the geology, with varying contribution from hydrothermal waters and minor anthropogenic factors predominantly affecting the tributaries. The significant proportion of Jurassic and Cretaceous carbonate rocks is reflected in the high to moderate pH, high alkalinity and major ions dominated by bicarbonate and calcium. The high alkalinity in the river acts as a buffer to any acidic inputs, be they geological or from anthropogenic factors such as mining or agriculture, and means that the river is able to safely support many aquatic species such as trout and shrimp.

Title: Remote sensing and environmental change of the Cañete valley

Abstract: We use satellite images to analyze the vegetation around the Cañete Valley. Vegetation indices provide a quantitative measure for vegetation cover as well as large-scale changes in the past 20 years. We find two major types of changes. One is caused by seasonality and the other is a response to trend changes over the past two decades. We identify key points of interest along the Rio Cañete and its associated tributaries. We also promote the need for gathering ground truth information to confirm hypotheses that arise from remote sensing observations.

Rio Cañete: Field laboratory

In November 2019 a group of UNDC staff and students accompanied the UCAM team up the valley for two days and one night to collect water and sediment samples, measure river channel characteristics and take drone footage of the sites. We stayed in Catahuasi and set up a temporary field laboratory in the hotel dining-room. Before dinner, we processed and prepared the water and sediment samples for analysis both later that evening and at laboratories in Lima.

En noviembre de 2019, un grupo de personal y estudiantes de la UNDC acompañó al equipo de la UCAM al valle durante dos días y una noche para recoger muestras de agua y sedimentos, medir las características del canal del río y tomar imágenes con drones de los sitios. Nos alojamos en Catahuasi y montamos un laboratorio de campo temporal en el comedor del hotel. Antes de cenar, procesamos y preparamos las muestras de agua y sedimentos para analizarlas esa misma noche y en los laboratorios de Lima.

Rio Cañete: Field laboratory

After dinner, the UCAM team, and UNDC staff and students carried out various tests on the water samples, including titration - a test of alkalinity levels. Staff and students were required to adopt the same health and safety measures as in the Lunahuana laboratory - laboratory coats, gloves and at times, protective glasses.

Después de la cena, el equipo de la UCAM y el personal y los estudiantes de la UNDC realizaron varias pruebas con las muestras de agua, incluida la ‘titración’, una prueba de los niveles de alcalinidad. Los docentes y estudiantes debían adoptar las mismas medidas sanitarias y de seguridad que en el laboratorio de Lunahuana: batas de laboratorio, guantes y, en ocasiones, gafas protectoras.

At site RC12 (Villarma) it was possible to use the OTT flowmeter in the main river channel from the bridge running from the road into the hotel. The flowmeter had to be used at its full extension in the deep, fast flowing river - a three man job! However, a combination of UCAM, and UNDC staff and stduents ensured that accurate readings were obtained.

En el sitio RC12 (Villarma) fue posible utilizar el caudalímetro OTT en el canal principal del río desde el puente que va de la carretera al hotel.

Rio Cañete: Shrimp processing in the field

N.Idros and H.Lepage (UCAM) with J.Jhoncon and K.Sanchez (UNDC) plus UNDC students prepare shrimp samples in the field at site RC00B (Boca de Rio) for further processing. The heptopancreas was extracted to analyse the diet of the shrimp while shrimp flesh samples were taken for DNA and heavy metal analysis. A small portable fridge (white box on table) kept the samples preserved until we were able to return to the Lunahuana laboratory. The shells were later dried and taken to Bournemouth University, in the UK, for heavy metal analysis. UNDC staff and students were able to participate in all aspects of the processing.
