Second Policy Forum focused on clean shipping

In May, SNOOP arranged the second Policy Forum in Turku in cooperation with Baltic Sea Forum. The Forum was arranged in a very apropos place for a maritime project thus the Forum took place at the venue of Maritime Centre Forum Marinum. During the 3½ hour session was given five very different but extremely interesting presentations about shipping-induced air emissions and solutions for cutting down the emissions. Jorma Kämäräinen from Trafi presented the HELCOM NECA – Designation of the Baltic Sea as a NOx Emission Control Area and Jukka-Pekka Jalkanen from Finnish Meteorological Institute presented the first results of SNOOP: dispersion of SO2, NOx and PM2.5 in Helsinki and Turku harbour regions. Wärtsilä’s marine environmental solutions were presented by Juha Hoppela from Wärtsilä and Kari Pihlajaniemi from Viking Line told about Viking Line’s solutions for clean shipping. Esko Pettay from Biota Tech shared information about Gaiamare’s biofuel innovation. After SNOOP Policy Forum, the participants were able to participate in the Baltic Sea Forum arranged by Centrum Balticum.

Emission inventories cover the years from 2005 to 2009

Emission inventories for the Baltic Sea shipping generated during the project cover now the years from 2005 to 2009 as emission inventories in 2005 have been finalised and the result analysis is in progress. Quality control work, which is essential for the project results, continues still and comparisons between model results and ship owner fuel reports have been conducted as planned.

The researchers of the project have continued developing of an interview template, which is used to collect ship behaviour data. International regulations on ship fuel sulphur content have changed, which causes the need of new data in order to develop the emission model further. Also collecting of behaviour data and data analyses have been started. In addition to this the researchers have been discussing with Finnish ship owners association and Trafi how to improve data collection and how to update the knowledge on international regulations concerning ship exhaust emissions. All this is particularly quality control work for the emission modelling and estimations but also for future scenarios' background data.

Marine model simulations performed

In WP3, marine response model simulations were performed using physical forcing, nutrient conditions in the water column and river inflow with nutrient loads corresponding to years 1997 (warm summer) and 1998 (cold summer). These two years were simulated with the same atmospheric and ship deposition of NOx. Cumulative chlorophyll a content in the upper 10-m layer during spring and summer cyanobacterial blooms was calculated for the central and western Gulf of Finland. The main result was that taking into account ship deposition the spring bloom chlorophyll content increased about 1% in both years but chlorophyll content of cyanobacterial bloom decreased in both years. The results of the marine response model simulations can be loaded here.

WP4 progresses in schedule

WP4 activities have progressed as planned. Measurements of NO, NO2, SO2 and PM2.5 in Turku near harbour, as well as in Helsinki and in Tallinn have continued according the activity plan. Data from Helsinki harbour area has been reported in HSY’s annual air quality report and real time air quality data is available also in HSY’s Internet pages. Calculations of PM2.5 dispersion and concentrations in Helsinki and Turku have been performed with the urban model. Project partners have started preparations for the health studies.

At the isle of Harmaja researchers selected the best place for the measurement site. The project got the permission for conducting measurement campaign in April. At the isle of Aegna we made some changes for the previous measurement set up and the measurement mast is now 15 meters tall. We also constructed the system for direct measurements of CO2 flux by eddy covariance method.
